SFPD released surveillance video related to killing of Oakland high school teacher

San Francisco police released surveillance video Wednesday of three "persons of interest" in a shooting death of a popular Oakland high school teacher outside a nightclub on Folsom street near 11th street, south of market.

The shooting happened June 18th.

The mother of the man who was killed, Carlo Tateo, is asking the public to help police find the killers.

"We just want this resolved so the community is safer than it is now," said Sonja Tateo.

The 31-year-old Tateo was a well-liked physical education teacher and football coach at Skyline High School in Oakland – Tateo's alma mater.

Days after the shooting, grief-stricken students gathered in Tateo's honor in the Skyline gym.

The video shows three people, two men and a woman walking on Folsom Street moments before encountering Tateo

"At the time of the incident two of the suspects began to harass some female members of Mr. Tateo's group. Mr. Tateo asked them to stop and move along. Without any provocation one of the suspects took out a firearm and without any provocation shot him," said San Francisco police Cmdr. Greg McEachern

Police say the people in the video then quickly drove off.

But they had been loitering on Folsom street for quite a while before the shooting.

"Every homicide is tragic. But this homicide is senseless," said McEachern

Police and Tateo's family hope someone will recognize the people in the video and come forward.

"What I would like to ask the public is to take close looks at the photos and if you recognize someone please make a phone call. We don't want this to happen to another famly," said Sonja Tateo.

The Skyline High School football team is dedicating the season to Tateo.
