The incident happened shortly before 11 a.m. at Cortez Park, off Tam O Shanter Drive.

Investigators say the incident began as a stabbing, but turned into a shooting after the good Samaritan tried to break it up.

The man who was killed has been identified as retired police department Officer Lauritus “Pepe” Petersen. He was 75 years old.

“He fell down and he was crying out for help,” resident Albert Gayotin said, who saw this unfold from his home just two doors down from the crime scene.

Petersen’s law enforcement career spanned more than 30 years. He was hired with the Stockton Police Department on Sept. 9, 1968 and worked with the department until 1998.

Petersen worked in both the department’s patrol and investigation’s divisions.
