Video (00:48) : Lois Riess has been on the run from the law for more than three weeks after allegedly killing her husband and a woman in Florida. 
 
 Lois Riess, the Minnesota grandmother with a gambling addiction, was captured Thursday night in South Texas, far from where she allegedly killed her husband in Minnesota and a woman who looked like her in Florida, according to local and national authorities. 
 
 Riess was arrested without incident in a restaurant in the resort area of South Padre Island, just north of Mexico, at 8:25 p.m. Thursday by two deputy marshals, said John Kinsey, deputy U.S. marshal in Florida. She was spotted by citizens, who alerted authorities. 
 
 The grandmother of five is suspected of killing her husband in Blooming Prairie, Minn., in late March and Pamela Hutchinson in Fort Myers Beach, Fla., earlier this month. 
 
 Authorities said Riess is in the San Pedro Island jail, and that they are working with Florida and Minnesota investigators to determine where she will be sent next. The white Acura she is suspected of stealing from Hutchinson was nearby and is being combed for evidence, they said. 
 
 “I promised all along that Lois Riess would end up in a pair of handcuffs,” said Carmine Marceno, undersheriff in Lee County, Fla. “Tonight, she sits in a jail cell in Texas,” she said in a statement. “We are working as expeditiously as possible to bring her back to Lee County to face murder charges.” 
 
 Riess had last been spotted north of Corpus Christi, Texas, on April 8 — just three hours north of where she was arrested.

 The U.S. Border Patrol had been put on alert and Mexican authorities were notified to be on the watch for anybody trying to use Hutchinson’s ID, said Lee County Sheriff’s Office spokesman Tony Schall. 
 
 Riess, who likes to visit casinos, began her cross-country flight after she allegedly killed her husband, David, in their Blooming Prairie home in late March. She then drove the family’s Escalade to Florida. The vehicle was found abandoned at Bowditch Point Park in Fort Myers Beach, the Lee County Sheriff’s Office said. 
 
 Sometime after dining at a Fort Myers Beach brewery on April 5 with Hutchinson, Riess shot Hutchinson and made off with her cash, credit card, white Acura and identity, authorities say. Marceno said Riess likely targeted Hutchinson because the two women bore a striking resemblance. 
 
 On April 6, Riess used Hutchinson’s credit card to pay for a hotel room in Ocala, Fla., authorities said. She also used Hutchinson’s ID to make a $5,000 withdrawal from a Wells Fargo Bank, and she withdrew another $500 from Hutchinson’s account while she was in Ocala. Riess also tried to make a $200 purchase at a gas station in Louisiana, authorities said. 
 
 Lee County authorities called Riess a “coldblooded killer,” and this week U.S. marshals elevated the search for her to “major case” status. That put her among offenders considered to be some of the country’s most dangerous individuals. 
 
 Riess has been charged with murder, grand theft of a motor vehicle, and grand theft and criminal use of personal identification in Florida. She also faces second-degree murder charges in Dodge County, Minn., where she transferred nearly $10,000 from her husband’s business account into his personal account and then forged his signature on three checks to herself for $11,000, according to theft charges recently filed in Minnesota. 
 
 Some in her southern Minnesota prairie town of 2,000 people speculated that Riess snapped because of gambling debts.

 MINNEAPOLIS (AP) — A Minnesota woman who is wanted in connection with her husband's death is now charged with killing a Florida woman who resembled her and stealing the woman's identity as she eluded authorities, officials said Friday. 
 
 Lois Riess, 56, of Blooming Prairie, Minnesota, has been charged in the shooting death of Pamela Hutchinson, 59, of Bradenton, Florida. Authorities were called to an area of Fort Myers Beach on Monday and found Hutchinson dead, with gunshot wounds. 
 
 Authorities aren't aware of any connection between the two women, but they believe Riess shot and killed Hutchinson to assume her identity. 
 
 "Ms. Hutchinson's purse was found to be in disarray and all cash, credit cards and identification appeared to be removed," Lee County Undersheriff Carmine Marceno said, adding: "Further investigation revealed that Ms. Hutchinson was targeted by the suspect due to the similarities in their appearance." 
 
 Riess is believed to be driving Hutchinson's car, a white Acura TL with Florida license plate Y37TAA. The car has been seen in Louisiana and Corpus Christi, Texas, since Hutchinson died. Riess' 2005 white Cadillac Escalade was found abandoned in a Florida park. 
 
 Riess is wanted in Florida for murder, grand theft of a motor vehicle and grand theft and criminal use of personal identification. Her current whereabouts are unknown. 
 
 "Riess's mode of operation is to befriend women who resemble her and steal their identity," Marceno said. "U.S. Marshals are actively involved in a national search for this dangerous fugitive. Riess is considered armed and dangerous and should not be approached if located." 
 
 Riess is also wanted in the March death of her husband, David Riess. Prosecutors are preparing second-degree murder charges in that case. Minnesota's Dodge County Sheriff Scott Rose said Friday that authorities believe the same gun was used in both killings. 
 
 Anyone who sees Reiss is urged to call 911, and anyone with information on her whereabouts is urged to call the Minnesota Bureau of Criminal Apprehension or Florida authorities. 
 
 Riess has been on the run since at least late March, after David Riess's business partner called Dodge County authorities on March 23 to ask them to check on him. The partner said no one at work had seen David Riess in over two weeks. 
 
 Authorities found David Riess's body inside his home with multiple gunshots. They couldn't determine how long he had been dead, and investigators could not find his wife. 
 
 During the investigation, authorities learned that Lois Riess may have been at Diamond Joe's Casino in Iowa. Authorities from Dodge County, the BCA and the Iowa Division of Criminal Investigation went to the casino, but Riess had already left. Authorities later learned she was in south Florida.

 "Our suspect is absolutely armed and dangerous. ... She may look like anyone's grandmother or mother but behind that smile is a cold-blooded murderer," Lee County Undersheriff Carmine Marceno told ABC affiliate WZVN-TV.

 This weekend, authorities kicked off a cross-country manhunt for Riess of Blooming Prairie, Minnesota, whom they suspect of also shooting her husband, David, dead at their Minnesota home March 23 and then taking off in their car. 
 
 Marceno said Riess "loves casinos" and has a "gambling problem." 
 
 Police said that after she allegedly killed her husband, Riess made a stop at an Iowa casino. Then the trail went cold for two weeks. She then made her way to Fort Myers, Florida, where, police said, she befriended Hutchinson. 
 
 Hutchinson looked like Riess, police said, and they allege Riess' mode of operation was to befriend women before stealing their identity. Police in Fort Myers Beach, Florida, identified Riess as a suspect in Hutchinson's death.

 Police said Riess allegedly drove Hutchinson's car to Corpus Christi, Texas, where it was last spotted. Marceno said she may be in Mexico. 
 
 "Our main fear is once her resources, once she diminishes all her resources, that she will be desperate and she will commit another act of violence," he said. "We don't want any more acts of violence or God forbid murder. ... She's on the run and we need to do everything we can to bring her to justice." 
 
 Riess has three adult children and is a grandmother as well, according to Dodge County Sheriff Scott Rose. She has no criminal record, according to authorities. She is now wanted for murder, grand theft auto and identity theft.

– Police in two states are looking for a 56-year-old woman accused of a bizarre double slaying. Authorities say that Lois Riess first shot to death her husband in Blooming Prairie, Minnesota, last month, reports WBBH. Riess than allegedly fled to Florida, where she was hiding out in Fort Myers Beach. There, police say she killed 59-year-old Pamela Hutchinson on Monday solely because Hutchinson bore a resemblance to her, and Riess wanted to assume her identity. Riess allegedly ransacked the woman's apartment and stole her cash, credit cards, and forms of ID. Riess is believed to be on the run again—in Hutchinson's white Acura with Florida plates—and authorities suspect she's on her way to Texas. "Riess's mode of operation is to befriend women who resemble her and steal their identity," says Lee County Undersheriff Carmine Marceno, per the AP. She's considered armed and dangerous.
