A 79-year-old man was arrested Friday night after he stabbed his wife and son-in-law during an assault at his home in Mira Mesa, police said.
The incident occurred at the suspect’s home in the 9800 block of Galvin Ave. just after 5:30 p.m., according to a media release.
The suspect thought that his family was poisoning him with the medication they were giving him, said Officer David Stanford.
At some point in the evening, the suspect took out a knife and stabbed his 80-year-old wife on the top of the head, Stanford said.
As the suspect’s son-in-law tried to intervene, the suspect allegedly stabbed him in the back and neck.
The suspect’s daughter, 40, was also cut on her index finger when she attempted to help the other victims.
The victims were taken to Scripps Medical Center in La Jolla with non-life threatening injuries.
The suspect was arrested at the scene for assault with a deadly weapon.
