SAN DIEGO (CBS 8) - San Diego police are investigating the murder of an 80-year-old woman who was found with blunt-force trauma all over her body, and investigators say her son is a suspect.
Around 10:30 p.m. in the 4800 block of Tinasa Way police say a relative checking on Joan Robinson found her body on the kitchen floor of her home.
According to neighbors, they were not shocked at hearing of the woman's death. They told News 8 police had been called to the home several times because of the victim's mentally ill 50-year-old son, identified as Dale Robinson.
"We worried about this for years and years, and we all tried to do something about it. We called the police when he got violent. We were scared and worried for Joan all the time," neighbor and friend Donna Warlick said.
Court records show Dale Robinson is on parole and has a long criminal history. In 2011 he pleaded guilty to felony battery and driving under the influence of methamphetamine. In 2002 he was convicted of felony theft. In 1988 he served time in prison for arson and destruction of property.
Shortly after the murder, investigators say Dale Robinson was involved in a traffic accident Sunday on Interstate 15. He is being treated for serious injuries at a local trauma center. Investigators plan to interview him once he recovers.
An autopsy is scheduled to determine the cause of Joan Robinson's death.
