San Diego man arrested on suspicion of stabbing wife and son-in-law

A 79-year-old San Diego man was arrested Friday on suspicion of stabbing his 80-year-old wife and 49-year-old son-in-law because he thought they were poisoning him with medication, police said.

The man's 40-year-old daughter was cut on her finger during a melee at the family home in the Mira Mesa neighborhood.

The suspect was arrested on charges of assault with a deadly weapon. His wife was taken to a trauma center with a knife wound on the top of her head and his son-in-law with stab wounds in his back and neck, police said.

None of the wounds are considered life-threatening, police said. No names were released. The Police Department's domestic violence unit is investigating.
