A woman police believe killed her husband in Minnesota - and a lookalike in Florida - was captured in Texas late Thursday, authorities said.
Marceno said law enforcement is now determining whether Riess will be returned to Minnesota or Florida to face her murder charges.
Riess, 56, of Blooming Prairie, Minnesota, was last seen Sunday, about 50 miles from Corpus Christi, Texas, heading south on Highway 77, Deputy US Marshal John Kinsey told CNN.
Marceno said the help of local and national media helped capture Riess. Amazingly, even as police and US marshals searched for her, Riess hung around the Kosters' neighborhood for a full week, walking the streets and eating at local restaurants.
A nationwide search has resulted in the Texas arrest Thursday of a grandmother accused of murder in two states - who police said befriended a look-alike to steal her identity.
Riess has been charged with murder, grand theft of a motor vehicle, and grand theft and criminal use of personal identification in Florida as well as second-degree murder charges in Dodge County, Minn. Riess' purported penchant for the slots lent her the nickname "Losing Streak Lois". Authorities said they believe she stole his money to go gambling in Iowa before traveling to Florida.More news: E. coli outbreak linked to romaine lettuce expands to 16 states

"It's alarming that there's somebody that's capable of doing such a heinous act", she said.
Hutchinson was found dead in her Fort Myers timeshare days later. Authorities say an eyewitness spotted a woman matching Riess' description at a restaurant on South Padre Island. Her apprehension was "truly a team effort on our part", Rose said in complimenting his staff of 54 at the Dodge County Sheriff's Office. "Our detectives are on the ground right now working to see exactly where she will be", said Marceno. "Tonight, she sits in a jail cell in Texas", she said in a statement.
Kinsey says he doesn't find it particularly unusual that Riess did not resist arrest. "Furthermore, no mater where she went, no matter where she hid, we were going to get her".
In a separate press conference held in Fort Myers Beach, Florida, Friday morning, Undersheriff Carmine Marceno of the Lee County Sheriff's Office said that he was not surprised in any way whatsoever that Riess offered no resistance when she was arrested.
The day her husband's body was found, investigators say Riess drove to a bank in Glenville and cashed over $10,000 in stolen and forged checks from his bank account.
