INDIANTOWN ― In a boardinghouse with multiple families, a man stabbed his wife in front of their young daughter Monday evening, Martin County sheriff’s Chief Deputy John Budensiek said.

The woman died from her wounds en route to HCA Florida Lawnwood Hospital in Fort Pierce.

Pedro Mateo-Andres, 39, of Indiantown, was arrested at the residence and faces a charge of first-degree murder.

Deputies arrived at the house in the 14000 block of Southwest Cherokee Drive around 5 p.m. to find Mateo-Andres on top of a woman who had multiple stab wounds, Budensiek said.

The chief deputy said Mateo-Andres told investigators he stabbed his wife because he believed she was cheating on him and planning to leave him.

The couple’s daughter, who is about 3 or 4 years old, witnessed the stabbing, Budensiek said.

She was taken to the Sheriff’s Office briefly so the Florida Department of Children and Families could find a place for her to stay.

The stabbing happened as other families were in the house, and one of the adults called 911 during the attack.

Deputies arrived soon after they received the call, kicked down a door and found Mateo-Andres on top of the woman.

“The suspect − immediately when (deputies) came in the door − was kind of surprised and was taken into custody by them,” Budensiek said.

The woman was airlifted to the hospital, but died on the helicopter.
