RAMONA, Calif. - Homicide detectives continued to investigate Monday the fatal shooting of a 34-year-old man in Ramona.

The shooting at a home in the 1300 block of Walnut Street occurred about 3 p.m. Sunday, according to San Diego County sheriff's Lt. Glenn Giannantonio.

The man went to the home and got into an argument with the homeowner, who told investigators the man was a stranger to him, the homicide lieutenant said in a statement.

As the man and the homeowner fought, the homeowner's adult son grabbed a gun from the home and ordered the man to leave at gunpoint, Giannantonio said. A struggle for the weapon ensued.

"The man was shot by the homeowner," Giannantonio said.

The victim – who was shot in the abdomen – was airlifted to Palomar Medical Center in critical condition, according to Cal Fire. He later died. His name was withheld pending notification of his next of kin.

Sergeant Gary Crowley of the San Diego County Sheriff's Department confirmed to 10News Sunday that the shooting took place on the dirt driveway of the home.

10News learned that 52-year-old Miles Lockhart is listed as the owner of the home and that he does not appear to have a prior criminal record.

A man in a wheelchair spoke with one investigator by the mailbox of the home and was taken to the sheriff’s substation at about 5 p.m. for questioning.

Three people inside the home were also taken to the substation for questioning as witnesses. 10News was told they are all cooperating.

No arrests had been made as of early Monday, according to Giannantonio.
