SEMINOLE, Fla. (AP) - A 23-year-old man is accused of killing his mother in Pinellas County.

Kevin Kyne was arrested and charged Sunday with first-degree murder. He's being held at the county jail until his first court appearance. It was not immediately known if he has an attorney.

Authorities have not said how 49-year-old Diane Kyne was killed, although they said there was evidence of upper body trauma. An autopsy will be conducted Monday.

The sheriff's office said deputies responded to a 911 call from the Kyne home and found the woman in her bedroom. Kevin Kyne and his parents had been arguing over a computer and the parents decision to make him move out of the home.
