On Monday, authorities identified two more possible victims. Both incidents happened in April 2021.

In the first incident, on April 10, police said a 40-year-old man was shot and killed in the early morning hours in Oakland. Six days later, a 46-year-old woman was shot at Park and Union street in Stockton; she survived her injuries.

All of the now six murders have been committed in dimly lit areas with the victims being ambushed and then shot.

Investigators have used ballistic evidence and other similarities – including when the victims were killed and how – to connect the crimes. Still, detectives have said they weren't sure if more than one person is responsible for the spree.

A grainy image of a person of interest wanted in connection to the case was previously released by police.

Also on Monday, authorities released the names of the five 2022 victims

The reward for information leading to an arrest has now reached a total of $125,000. The City of Stockton, Crime Stoppers, and even the owner of a local construction company have put up the money. 

Forensic psychologist on serial killer behaviors, personality 

Dr. Robert Schug, a forensic psychologist and professor of criminology and forensic psychology at California State University Long Beach, said there's no one person who may be a serial killer. 

"Oftentimes we suspect there's stability to their lives, having a job, place to live, whatnot." said Schug. 

He said there's a spectrum of behaviors, sometimes linked to mental illness, but there's no one definition for the person that may take on these traits. 

"We don't want to rule anything out, just because he's killing Hispanic men, that he'll only and always kill Hispanic men." said Schug. 

He said many of the answers to questions CBS13 has now, many only be answered when the person or persons are found.
