SOUTH PADRE ISLAND, Texas — The Latest on the arrest of a woman suspected of killing her husband in Minnesota and a woman in Florida (all times local):

3 p.m.

A county sheriff in Minnesota says his office is preparing charges to build what he calls "the strongest case" against a woman suspected in the deaths of her husband and a woman in Florida whom she resembled.

Dodge County Sheriff Scott Rose says he's relieved that 56-year-old Lois Riess was arrested Thursday at a restaurant in South Padre Island, Texas, after a witness recognized her photo and called police.

Riess had been on the run since at least late March, when her husband, David Riess, was found fatally shot at their home in Blooming Prairie, Minnesota. Investigators believe she used the same gun to fatally shoot 59-year-old Pamela Hutchinson of Bradenton, Florida. They believe she killed the woman to assume her identity.

It's unclear where Riess will be tried first.

Authorities say a woman suspected in the deaths of her husband and a woman in Florida had checked into a South Texas tourist town motel and was socializing in a bar when she was arrested.

South Padre Island Police Chief Randy Smith says a witness called police after recognizing 56-year-old Lois Riess from a photo. He says two undercover officers approached Riess Thursday evening, and that she did not resist arrest.

Smith says Riess hasn't been questioned because police are waiting for other agencies to arrive in South Padre Island, a beach community 27 miles (43 kilometers) from Mexico.

Riess had been on the run since at least late March, when her husband, David Riess, was found fatally shot at their home in Blooming Prairie, Minnesota. Investigators believe she used the same gun to fatally shoot 59-year-old Pamela Hutchinson of Bradenton, Florida. Hutchison was found dead April 9.

Smith says Riess wasn't armed when she was arrested.
