TRACY -- Police in Tracy are investigating a homicide near Gretchen Talley Park.
Officers responded to the scene near Dove and Egret Drive shortly after 9 p.m. to find a man in the road with a "traumatic injury." The victim, 64-year-old Parmjit Singh, was pronounced dead at the scene.
"It happened somewhere inside the park and he managed to stagger outside of the park and he collapsed right here on the sidewalk," said neighbor Dave Roychowdhury.
Detectives say a passerby spotted the man bleeding on the ground and immediately called 911.
Roychowdhury said Singh has lived across from the park for the last decade and had never seen anything like what he saw Sunday night.
"A neighbor came and she knocked at my door and as I came out I saw a multiple number of police cars and the fire truck and ambulance all here. And the medical people were trying to revive the gentleman across from my house," he said.
First responders rushed to the park to find Singh bleeding heavily from a stab wound.
"Absolutely speechless. It's absolutely senseless. What happened is beyond comprehension," Roychowdhury said.
Monday night, the police department released surveillance footage of a person running through the area of Gretchen Talley Park around the time of the homicide. Investigators are now searching for that person.
Neighbors said Singh lived nearby and would walk in the park almost every day.
"Elderly Sikh gentleman. Very friendly," Roychowdhury said. "He used to walk around, sit in the park in the evening, meet with people and go about his everyday routine."
Some residents are worried Singh may have been attacked because he was Sikh. Detectives told FOX40 they understand people's concerns and say they are actively investigating all leads and possible motives.
The attack has left the neighborhood shaken. Neighbors said they are all deeply saddened by what happened.
"Absolutely stunned. This is a very safe neighborhood, very decent area of Tracy," Roychowdhury said. "Nothing has ever happened like this here."
Tracy Mayor Robert Rickman released a statement following the homicide:
We take pride in our safe, close-knit community. The loss of one of our own to violence has shaken us to our core and is felt by the entire community. On behalf of the Tracy City Council, we offer our sincerest condolences to Mr. Singh’s family, friends and to the members of our Sikh community.
