When a man died after a coffee shop altercation last month, police were cagey on if his death was misadventure or homicide. A month later, and the decision appears to have been made, and the San Francisco Police Department is circulating footage of the suspect in the crime.

It was a little before 8 a.m. on Thursday, October 1 when 60-year-old SF resident Marc Garcia walked into a coffee shop on the 1400 block of Van Ness, which is between Bush and Pine Streets, SFPD spokesperson Officer Albie Esparza said at the time.

While in the coffee shop, Esparza says Garcia had a physical confrontation with a 30-something, dark-haired man wearing white pants and a blue zippered jacket, and carrying a blue messenger bag.

After the altercation, Garcia staggered out of the coffee shop and collapsed on the street. He was transported to San Francisco General Hospital, where he was pronounced dead.

Since then, police have sought the blue-jacketed man for questioning, and Monday released surveillance footage of the homicide suspect. Here it is:

According to SFPD spokesperson Officer Carlos Manfredi, police believe that the suspect "was working in the construction trade in San Francisco on the day of the assault."

It's worth nothing that there is a Peet's Coffee at the corner of Bush and Van Ness, as well as a Starbucks at the corner opposite. Esparza declined to specify which establishment was the site of the assault when asked in October, and SFist's efforts to get clarification on the location since have been unsuccessful.

Despite SFPD's unwillingness to name the scene of the attack, police are hoping that anyone with information on the suspect will contact SFPD's anonymous tip line at 415-575-4444 or will text-a-tip to TIP411 and begin the message with SFPD.
