The home of Christy Martin, the world's best-known female boxer, was burglarized while she was hospitalized after being shot and stabbed Tuesday by her husband, Orange County (Fla.) deputy sheriffs said.

James Martin, 66, remains at large, the Orlando Sentinel reported.

Christy Martin, 42, flagged down a motorist Tuesday evening and the motorist took her to Florida Hospital-Apopka, where doctors determined she had been shot and stabbed in the torso and left leg, deputies said. She told deputies she was attacked by her husband when she returned to her home after being away for a few days.

A friend went to the home the next afternoon to pick up some personal belongings for Christy Martin and called the Sheriff's Office because it appeared the home had been burglarized, sheriff's spokesman Jim Solomons said.

When deputies arrived, they checked out the house and found no one inside but confirmed it had been burglarized, Solomons said. Investigators have not said what, if anything, was stolen, but said they have no suspects, Solomons said.

In the early 1990s, Martin signed with promoter Don King, who placed her in several pay-per-view fights. She once boxed on an undercard for Mike Tyson. Most recently, she and her husband operated a boxing gym in Apopka, where they trained amateur boxers.

Records indicate deputies were twice called to the couple's home Tuesday. An out-of-state caller contacted the Sheriff's Office to report Jim Martin was distraught about the relationship with his wife and was suicidal. The caller also said there were weapons in the home.

Anonma, who plays for German club USV Jena, reportedly told the BBC that she has already been gender tested, which she found "offensive." Equatorial Guinea qualified for next year's World Cup in Germany.
