GILBERT, Ariz. -- Police have accused a 23-year-old Gilbert woman of trying to kill her estranged husband by stabbing him in the chest with a kitchen knife while they were having sex, Phoenix television station KPHO reported.

Gilbert police said Falon Gonzales and her husband, 26-year-old Juan Carlos Gonzales, were having marital problems. The pair was separated and Juan Gonzales had filed for divorce last month.

Police said Falon Gonzales stabbed her husband in his home on Tuesday, then fled the scene.

Juan Gonzales went to a neighbor's house for help. He was taken to a Scottsdale hospital in serious condition with a collapsed lung.

Police said they found Falon Gonzales in a home about two miles away. She was taken to a Gilbert hospital with a hand laceration.

Falon Gonzales told officers Juan Gonzales had left the home one month ago and ended their marriage.

Police said she received a telephone call from Gonzales on Tuesday morning requesting she meet him at their home to have the home appraised.

Falon told police that after she arrived at the home, and while waiting for Gonzales to arrive, she contemplated whether to harm him by stabbing him with a kitchen knife that she placed in a duffle bag.

She told police she put the knife in the duffle bag for the purpose of injuring him after she lured him to the bathroom to have sexual intercourse, police said.

Gonzales and the appraiser arrived and once the appraiser left, Gonzales showed her dissolution of marriage papers, according to her account to police.

Falon said she began to cry and Gonzales consoled her, officers said. They began kissing and she later suggested they enter the master bedroom bathroom to have sexual intercourse, according to her account.

Once disrobed, she told Gonzalez she was going to get sexual toys from the closet, officers said. She returned with the duffle bag containing the knife, police said.

During sex, Falon reached into the duffle bag, removed the knife and stabbed him in the chest, officers said.

She told police she said, "I'm sorry Juan." After she removed the knife from his chest, the two began to struggle for the knife, according to officers.

Gonzales was able to flee the home.

Falon Gonzales was arrested on charges of attempted homicide. A preliminary hearing has been set for Sept. 4. She is on supervised release under an electronic monitoring program.
