Detectives are still investigating the shooting death of a 48-year-old man in El Cajon, the suspect -- his mother.
The man was shot to death inside the home he shared with his parents in the 2200-block of Tina Street in an upscale neighborhood in unincorporated El Cajon.
Deputies got the call just after 11 p.m. Sunday about an assault with a deadly weapon.
While en route, deputies were advised that the reporting party, later identified as Josephine Mary Ring, 66, stated that she had shot her son Vincent John Bonfiglio, 48, according to a Sheriff's department news release.
When deputies arrived, they said they found Ring outside the home and her son lying on the floor inside the house.
Detectives wouldn't reveal what Ring said when she called 911, but right now she is in custody and is under medical supervision for an unknown reason. They are hoping to interview the mother to find out what may have led up to the shooting and if it was self-defense or accidental.
Officials believe Bonfiglio lived at this home with his parents.

The father, who lives with Alzheimer's, was at home during the shooting, but wasn't able to provide any information about the shooting, detectives said.
"At this point, we believe his mother is responsible for the shooting. However, we don't know the circumstances surrounding the shooting," said Lt. Dennis Brugos.
Tina Street has been cordoned off just before the private driveway leading up to the home where this deadly shooting happened. Neighbors say the family owns four homes that are on the property.
Neighbors said the family kept to themselves.
"We knew he lived with his mom, met him during the fires, that's the only time I knew he was there, we never see them," said neighbor Sheri Keyeski.
