A lawsuit filed Monday by 10 Sandy Hook victims’ families claims Adam Lanza would not have been able to kill 26 people in five minutes without his “weapon of choice,” a Bushmaster AR-15. 
  
 “The number of lives lost in those 264 seconds was made possible” by the rifle that was “engineered to deliver maximum carnage with extreme efficiency,” according to the lawsuit against AR-15 manufacturer Bushmaster. 
  
 The lawsuit was filed Monday morning in Connecticut superior court against Bushmaster, several other manufacturers, and Riverview Gun Sales, where Lanza’s rifle was purchased. 
  
 These defendants know that “as a result of selling AR-15s to the civilian market, individuals unfit to operate these weapons gain access to them... Despite that knowledge, defendants continue to sell the XM15-E52 rifle to the civilian market.” 
  
 In making the case against any civilian sales of AR-15s, the plaintiffs say—among other things—“there is not a single state that requires a mental-health examination of a potential purchaser of an AR-15” or to “answer questions about other individuals with whom they intend to share access.” 
  
 The reference is unmistakably to Nancy Lanza, who purchased the AR-15 that her son would use to massacre 20 first-grade students and six adults before taking his own life. 
  
 Under the title “The Road to Sandy Hook,” the lawsuit painstakingly details the use of the AR-15 in other mass shootings, including those at schools. Yet Bushmaster continued to market the AR-15 as a weapon that would make others “bow down” and kept selling high-capacity magazines with it. 
  
 After recounting the individual lives taken by Lanza and his Bushmaster AR-15, the lawsuit says the defendants “knew, or should have known” that the sale of the AR-15 “posed an unreasonable and egregious risk of physical injury to others.” In addition, it should’ve known it would’ve been used in a mass shooting to inflict maximum casualties. 
  
 The families created estates in their childrens’ names (with parents as administrators) so they could sue on behalf of the victims. Bushmaster and the other defendants’ conduct, the plaintiffs say, was a “substantial factor resulting in the following injuries and losses.” They are listed for the dead as “terror; ante-mortem pain and suffering; destruction of the ability to enjoy life’s activities; destruction of earning capacity, and death.” 
  
 The plaintiffs claim damages in excess of $15,000 and seek further relief for monetary damages, puntitive damages, attorneys’ fees, costs, and injunctive relief. ||||| In an article appearing on Today Parents, Nicole Hockley writes a letter to the mom she was before she lost her youngest son Dylan in the Dec. 2012 Sandy Hook Elementary School shooting. 
  
 "The tragedy changed every single aspect of your life, not only because of the obvious absence of your child, but because of the constant hole inside you that can never be filled," Hockley writes. 
  
 In the letter, Hockley goes on to talk about gun violence prevention and recognizing the signs of a troubled child, asking parents to get involved by talking to their children, other parents and educators about these issues. 
  
 "Small but meaningful actions create change," Hockley writes.

 A woman kneels with her children in front of bells which were being rung outside of St. Rose of Lima Church ahead of Sunday service on the two-year anniversary of the Sandy Hook Elementary School shooting in Newtown, Connecticut December 14, 2014. 
  
 NEWTOWN, Conn. Parents of almost half the young children killed by a gunman at an elementary school in Newtown, Connecticut, two years ago on Sunday have taken initial steps toward filing lawsuits tied to one of the deadliest school shootings in U.S. history. 
  
 For a second straight year the leafy suburb has planned no public events to commemorate the massacre, which left 20 first graders and six educators dead at Sandy Hook Elementary School, an incident that inflamed the U.S. debate over gun control. 
  
 The parents of eight of the children killed in the Dec. 14, 2012, carnage, which 20-year-old gunman Adam Lanza ended by shooting himself dead as he heard police sirens approach, have notified Connecticut courts that they may file wrongful death lawsuits in state or federal court. 
  
 Their initial court filings, related to legal entities created in memory of their children, do not indicate who the families could target in their lawsuits, according to a chief court clerk for North Fairfield County Probate Court. 
  
 While the parents could not be reached for comment, a spokesman for Bridgeport law firm Koskoff, Koskoff and Bieder said that a lawyer at the firm had recently met with some of the Newtown parents about potential suits. 
  
 "Attorney Josh Koskoff has met with parents about legal action," said Geraldo Parrilla, a legal assistant with the firm. 
  
 While Newtown grabbed the nation's attention, school shootings remain common across the United States. Some 95 incidents, including fatal and nonfatal assaults, suicides and unintentional shootings have taken place across 33 states since Newtown, according to Everytown for Gun Safety, a group created by the merger of Mayors Against Illegal Guns, founded by former New York Mayor Michael Bloomberg and Moms Demand Action for Gun Sense in America, a group founded after the attack. 
  
 "It's astounding," said Shannon Watts, who founded the Moms group. "There is no other developed country that would tolerate this kind of gun violence around school age children." 
  
 Gun-rights advocates note that the Second Amendment of the U.S. Constitution protects the right to bear arms and suggested after the attack that armed guards in schools could avert future violence. 
  
 Newtown, located some 78 miles (126 kilometers) northeast of New York City, has razed the school that was site of the attack and recently acquired the home where Lanza lived with his mother, who he shot dead as the first act of his rampage. That building may also be torn down. 
  
 Newtown plans no public ceremonies to mark Sunday's anniversary of the shootings. 
  
 "The second anniversary, like the first one last year, will be recognized in personal reflection and remembrance,” said Newtown's highest elected official, First Selectman Patricia Llodra, and Superintendent of Schools Joseph Erardi, in a statement ... “There are no formal or official ceremonies to be held by the town or school district." 
  
 But a 12-member commission that includes four parents of young victims of the attack is steadily moving ahead to create a permanent memorial to honor the dead. 
  
 "We are meeting monthly, but have taken December off out of respect for the families who lost their loves ones on that tragic day," said Kyle Lyddy, chairman of the Sandy Hook Permanent Memorial Commission that is entering its final phase of recommending either a single or multiple memorials. 
  
 Lyddy said the panel is considering such proposals as an outdoor park and gardens, and indoor murals and art exhibits. He said the commission has not set a deadline because "Our main goal is to get this right."

 They are working with an attorney who represented Michael Jackson’s family in a $1.5bn wrongful death lawsuit against his international concert promoter, and a Democratic lobbyist who worked in the Clinton administration and specialises in taking on major corporations, the Guardian has learned. 
  
  
  
 Parents of at least 13 of the 20 young children killed in the December 2012 shooting have in the past two weeks opened estates in their names at the regional probate court, a necessary first step in filing a lawsuit over their deaths. Eleven of these sets of parents checked a box specifying that they intended to make a wrongful death claim. 
  
 Sunday 14 December, the second anniversary of the killings, also marks the legal deadline for filing a wrongful death lawsuit over the incident in the civil courts. The Hartford Courant reported earlier this week that parents were discussing a legal action against Bushmaster, the North Carolina-based manufacturer of the AR-15 rifle that was used by Lanza. 
  
 Asked whether notice of a lawsuit had been received, an employee in the legal department of Remington Outdoor Company, Bushmaster’s parent firm, referred the inquiry to the company’s public affairs director, who then did not respond to numerous emails, phone calls and voicemails this week seeking comment. 
  
 The Guardian has confirmed that action is to be announced on Monday involving Michael Koskoff, a partner in the Connecticut law firm Koskoff, Koskoff & Bieder, who three years ago represented the Jackson family in their unsuccessful lawsuit against AEG Live, the promoter of a planned tour for which Jackson was rehearsing when he died in 2009. 
  
 Joining his firm in promoting the action is Karen Hinton, a lobbyist and PR expert who once worked for the Democratic National Committee and is a close ally of Andrew Cuomo, the governor of New York, who described her as “my public relations guru” in his 2003 book Crossroads: the Future of American Politics. 
  
  
  
 Hinton worked for Cuomo when he was housing secretary to then president Bill Clinton in the 1990s and is married to Howard Glaser, who was until earlier this year one of Cuomo’s most senior aides. 
  
 “We are not going to be speaking about that until Monday,” Hinton said of Sandy Hook, declining to confirm what the parents’ plans were. 
  
 Hinton, who states in her Twitter biography that she is “taking on big oil, big banks & other big bullies”, has represented clients including Ecuadorian villagers in a long-running multibillion-dollar legal battle with Chevron, the energy corporation, over pollution of the Amazon rainforest. 
  
 According to records reviewed by the Guardian at Fairfield county probate court, estates were opened with notifications of wrongful death claims this month for Charlotte Bacon, Daniel Barden, Dylan Hockley, Jesse Lewis, Ana Marquez-Greene, James Mattioli, Grace McDonnell, Emilie Parker, Jack Pinto, Noah Pozner and Jessica Rekos. Estates were also opened for Avielle Richman and Benjamin Wheeler, but the box signifying a wrongful death claim was not checked. |||||
Output:
Two years ago yesterday, Adam Lanza walked into Sandy Hook Elementary School and fired 154 bullets in less than five minutes, killing 20 small children and six educators. Today, the families of nine of the victims, along with a wounded teacher who survived, have filed suit against the maker of Lanza's "weapon of choice," the Bushmaster AR-15, reports the Daily Beast. "The number of lives lost in those 264 seconds was made possible" by the AR-15, which was "engineered to deliver maximum carnage with extreme efficiency," reads the lawsuit; also named are Remington and Riverview Gun Sales, which sold Lanza's weapon. The suit faults the gunmakers for making such rifles available "to the civilian market" despite knowing that "individuals unfit to operate these weapons gain access to them." Per the suit, Bushmaster's actions caused the plaintiffs "terror; ante-mortem pain and suffering; destruction of the ability to enjoy life’s activities; destruction of earning capacity, and death." The families of 13 victims had in recent weeks created estates for their children, a required step in filing suit, reports the Guardian, which notes not all of those families intended to sue. They are represented by the same lawyer who represented Michael Jackson's family against AEG Live. Despite calls for increased gun control in the wake of the Newtown tragedy, Reuters notes that school shootings remain largely unchecked, with 95 fatal and nonfatal incidents over the last two years. Meanwhile, Nicole Hockley, mother of Dylan Hockley and one of the parents who sued, has written a letter to the mother she used to be.
