An elderly man has been arrested after stabbing his ex-wife at their home in West West Miami-Dad, Local 10 News reports.
The 76-year-old man has stabbed the 71-year-old victim, from whom he has split for four months, said police, who had been called at home near Southwest 152 Avenue and eighth.
The suspect went to the home to visit the woman, but then went to the kitchen, grabbed a knife and started stabbing her.
Authorities said a teenager at home intervened and appeared unharmed. A group of roofs working in a nearby home confirmed that the granddaughter is running out, looking for help.
“We heard screams, we went to help us understand what was going on inside the house and saw the lady on the floor and the man standing above her with a knife,” a worker said.
“There was blood everywhere. We tried to tell him to put the knife. We threw different things to him to get him to get out of the wounded lady,” he added.
The victim was taken to the Regional Medical Center Kendall, where he died.
The identity of the suspect and the victim have not yet been released.
