Toronto police have released security camera images of someone they believe is a second suspect in a July 25 shooting homicide in the Annex.

In a news release issued Tuesday, police describe the second suspect as white, 5'9" and 150 lbs. with short, brown hair.

One suspect has been arrested and charged in connection with the death of Sebastian Herrera.

On Aug. 25, police arrested Marvin Jarrett, 22, in the Oakwood Avenue and Vaughan Avenue area and charged him with first-degree murder and attempted murder in connection with the slaying of Herrera.

The victim had been out with his girlfriend at the Brunswick House, a popular Annex bar for the student crowd.

They returned to their vehicle for a cigarette. The car was parked in a laneway south of Bloor Street between Major and Brunswick Streets.

As they prepared to return to the bar, someone confronted them. The suspect left his vehicle and allegedly robbed Herrera of a crucifix necklace. The suspect then shot Herrera in the stomach as the victim lay on the ground.

Herrera would die in hospital of his injuries, making him Toronto's 31st homicide victim of 2009. The total count is now 41.

Although Jarrett faces charges, no allegations have been proven against him in a court of law.

Another suspect had been sought as a possible suspect in the case, but that person turned themselves into police and were cleared following an interview.

Det. Stacy Gallant, one of homicide investigators working the case, say they believe the person in the images drove the car on the night of the shooting.

The security camera images were taken in the general vicinity of the shooting, but Gallant told ctvtoronto.ca he couldn't say much more as it could compromise the investigation.

The person in the photo is likely an associate of Jarrett's, "but we don't know who he is," he said.
