Problem:Det. Joseph Lemm 
  
 One of the six Americans killed in a suicide bomb attack in Afghanistan Monday was a New York police detective serving in the U.S. Air National Guard, NYPD Commissioner Bill Bratton said Monday evening. 
  
 Det. Joseph Lemm, a 15-year veteran of the department, was on routine security patrol with his convoy around Bagram Airfield north of Kabul around 1:30 p.m. local time when a suicide bomber drove a motorcycle into the convoy and blew himself up, NBC News reported. 
  
 The Taliban has claimed responsibility for the attack. 
  
 Gov. Cuomo released a statement Tuesday morning saying Lemm and the other five Americans killed will be "greatly missed." 
  
 "Staff Sgt. Joe Lemm was committed to his fellow Americans, and embodied the selflessness and bravery of the U.S. Armed Forces and the NYPD. I join all New Yorkers in mourning his loss, as well as the loss of the other victims of this horrific attack," he said in the statement. 
  
 Mayor de Blasio echoed the sentiment, noting that Lemm's death comes just a year and a day after the deaths of NYPD officers Rafael Ramos and Wenjian Liu, who were both gunned down while sitting in their patrol cars in Brooklyn in 2014. 
  
 "There can be no greater sacrifice than the one made by a member of our military or our police force, who put their lives on the line to protect Americans. Detective Joseph Lemm did both for 15 years. He gave his life, yet asked for little in return other than to serve his country and his fellow New Yorkers, who may not have known him in life, but mourn his death nonetheless," de Blasio said. 
  
 Six Americans in the convoy of U.S., NATO and Afghan forces were killed, including Lemm, while two other Americans and an interpreter were wounded, according to NBC News. 
  
 Lemm served in the Bronx warrant squad on the NYPD, and during his career on the force, he was also deployed three times, twice to Afghanistan and once to Iraq, Bratton said. He was promoted to NYPD detective in January of 2014. 
  
 The Air National Guard didn't immediately respond to a request for comment.

 Air National Guard Staff Sgt. Joseph Lemm, a 15-year NYPD veteran from Westchester County, died in the fiery blast that ripped into his unit, officials said. 
  
 The joint NATO-Afghan patrol was moving through a village near Bagram Airfield, the largest U.S. facility in Afghanistan, when the suicide attacker targeted the troop. 
  
 Two other American soldiers and an Afghan soldier were wounded, military officials said. 
  
 It was the deadliest attack on international forces since August. The Taliban claimed responsibility, authorities said. 
  
 “Our heartfelt sympathies go out to the families and friends of those affected in this tragic incident, especially during this holiday season,” Army Brig. Gen. William Shoffner said. 
  
 Lemm, 45, was on this third tour overseas. He leaves behind a wife, Christine, a teenage daughter, Brook, and a young son, Ryan. 
  
 Distraught relatives met reporters outside the fallen detective’s red-brick single-family home on a quiet West Harrison street Monday night.

 “We’re grieving,” said a woman. “Please respect that.” 
  
 Police Commissioner Bill Bratton said Lemm was promoted to detective third-grade in January 2014. He worked in the Bronx warrant squad. 
  
 “Detective Joseph Lemm epitomized the selflessness we can only strive for: putting his country and city first,” Bratton said. “Tonight, we grieve and we remember this selfless public servant who dedicated his life to protecting others.” 
  
 Lemm was also known for his off-duty heroics — in December 2005 he saw three teens running from the scene of a stabbing at a CVS pharmacy. He followed them in his own car, called 911 for backup and apprehended two of them on the spot. The third was hiding behind a car. 
  
 The president of Lemm’s union said the dedicated public servant was beloved and respected within the NYPD. 
  
 “Detective Lemm was very well-liked by his fellow officers at his command, and they are deeply saddened,” said Michael Palladino, president of the Detectives’ Endowment Association. “Joseph was a good cop and a good American, and we will miss him very much.” 
  
 Lemm is the third NYPD officer killed while serving overseas in Iraq and Afghanistan, the department said. The officer’s initial tour was in Iraq, from March to December 2011.

 He was then deployed to Afghanistan. His first tour ran from October 2012 through 2013. His second tour began in August. 
  
 In July 2013, the devoted dad returned home and snuck into a Rye Brook restaurant to hear his then-14-year-old daughter sing in an “American Idol”-type competition, according to News12. His secret arrival was also a thrill for his then-2-year-old son, Ryan, and his wife. Lemm told News12 he was looking forward to “pizza and a nice American burger.” 
  
 Mayor de Blasio lamented the “horrible news” of Lemm’s death. 
  
 “(It) serves as a painful reminder of the debts we owe to the brave men and women in uniform who put themselves in harm’s way ... to keep us all safe,” he said. 
  
 Gov. Cuomo also praised Lemm’s service. 
  
 “I join all New Yorkers in mourning his loss, as well as the loss of the other victims of this horrific attack,” he said.

 With ROCCO PARASCANDOLA ||||| An NYPD detective nicknamed “Superman” by his fellow cops was one of six US troops killed Monday in a suicide bombing in Afghanistan, where he was serving in the Air National Guard. 
  
 Detective Joseph Lemm, 45, of the Bronx Warrant Squad was killed when a bomb-laden Taliban assassin on a motorcycle targeted a joint American-Afghan patrol near a major US air base. 
  
 “Earlier today, we lost one of our Finest in a suicide bombing in Bagram, Afghanistan,” Police Commissioner Bill Bratton said Monday night. “Detective Joseph Lemm epitomized the selflessness we can only strive for: putting his country and city first.” 
  
 Lemm, a staff sergeant in the Guard, was nominated for a Post Liberty Medal in 2006 after he chased down a teen who had stabbed another youth. 
  
 He started out at the 48th Precinct and then moved to the Bronx Warrant Squad about five years ago. 
  
 Lemm, who lived in West Harrison in Westchester County, leaves behind a wife, Christine, and two children: a 17-year-old daughter, Brook, and 4-year-old son, Ryan. 
  
 The 15-year NYPD veteran and native of Nebraska was a third-grade detective who was promoted under Bratton in January 2014. 
  
 “He was a great cop, very active,” said an officer who worked with Lemm in the Bronx Warrant Squad. 
  
 Another cop who worked with Lemm called him a “strong, strapping guy,” adding that he “looked like Clark Kent,” which led to his “Superman” nickname. 
  
 “Everyone is in shock,” the officer said. “It’s another week before Christmas and we have another cop we have to worry about burying and taking care of his family.” 
  
 Lemm was deployed three times as a member of the NYPD, twice in Afghanistan and once in Iraq, Bratton said. 
  
 “Tonight, we grieve and we remember this selfless public servant who dedicated his life to protecting others,” Bratton said. 
  
 By Monday night, after members of the US Air Force notified Lemm’s family of his passing, his home was full of grieving family, friends and fellow cops, a source said. 
  
 “He was the best,” Lemm’s landlord told The Post. “All I know is that this is a horrible tragedy.” 
  
 A buddy in Westchester said, “Joe was a great man and a great friend. He was full of life. We used to play basketball together.” 
  
 On his Facebook page, Lemm paid tribute to other fallen NYPD officers, including Rafael Ramos and Wenjian Liu, who were murdered one year ago. 
  
 The Taliban attack marked the deadliest assault on international forces since August. 
  
 Secretary of Defense Ash Carter, in a statement, called the attack “a painful reminder of the dangers our troops face every day in Afghanistan.” 
  
 US Army Brig. Gen. William Shoffner, a Pentagon spokesman in Afghanistan, said, “Our heartfelt sympathies go out to the families and friends of those affected in this tragic incident, especially during this holiday season.”

Solution:
An NYPD detective nicknamed "Superman" was among the victims of the largest attack on foreign troops in Afghanistan since August. Air National Guard Staff Sgt. Joseph Lemm, a 15-year NYPD veteran who was on his third tour overseas, was one of six people killed when a suicide bomber on a motorcycle laden with explosives targeted an American-Afghan patrol near Bagram Airfield, reports the New York Daily News. Two US troops and an Afghan—identified as an interpreter, per NBC News—were wounded. The father of two "epitomized the selflessness we can only strive for: putting his country and city first," says Police Commissioner Bill Bratton. "We grieve and we remember this selfless public servant who dedicated his life to protecting others." Lemm was on his second tour in Afghanistan and previously served in Iraq in 2011. But he was known for his service even when off the clock. In December 2005, he helped apprehend two of three teens he saw running from the scene of a stabbing and was nominated for a Post Liberty Medal, reports the New York Post. "Everyone is in shock," says a colleague, noting Lemm earned the nickname "Superman" because he was a "strong, strapping guy" who "looked like Clark Kent." He was "a great man and a great friend. He was full of life," a friend adds. In 2013, Lemm surprised his family by returning from a 10-month tour in Afghanistan to watch his teenage daughter, Brook, sing in a competition, reports News12. Brook is now 17, while Lemm's son, Ryan, is 4. He's also survived by wife Christine.
