It's not much, they acknowledge, but Elk Grove police hold out hope that an updated description of a pickup truck might spur the one tip needed to solve the killings of two Sikh men almost one year ago.
Then, as now, the scene of the March 4 double homicide and the backgrounds of the victims themselves left little for investigators to go on.
But as the one-year anniversary approaches, detectives have compiled a new description of the vehicle they believe was used in the shootings, which felled 65-year-old Surinder Singh and his friend, 78-year-old Gurmej Atwal.
That vehicle is believed to be a "significantly and noticeably" lifted, full-sized, gold or tan pickup truck with a standard cab, Detective Kevin Papineau said in a news conference Wednesday.
The updated description is based on surveillance footage, a limited interview with Atwal before he died, and other statements given to police, Papineau said. Those sources, however, did not indicate the year, make or model, he said.
That afternoon, Singh and Atwal were walking along East Stockton Boulevard as part of their daily routine.
Detectives believe the truck pulled up and stopped, with someone inside firing gunshots at the men. Papineau declined to say how many shots were fired or what kind of gun was used.
He said the presence of shell casings over a 15-foot area indicates the gun was outside the truck when fired. Police, however, do not know whether the shooter got out of the truck or just reached out the window.
They also do not know how many people were involved only that the truck sped southbound on East Stockton Boulevard after the shooting, Papineau said.
Singh was dead when paramedics arrived. Atwal spent six weeks in the hospital during which investigators were able to have only a "very, very limited interview" with him before he, too, died.
Detectives have identified no motive in the case. Nor is there evidence to confirm or rule out the possibility of a hate crime, Papineau said.
Both men were Sikh a religion whose members have been mistaken for Muslims. They wore turbans and thick beards.
The scene held few clues, and none of the roughly 110 tips called in to police offered a viable lead. Officials hope to generate new leads.
The reward fund for information in this case stands at $57,000. Elk Grove police have applied for $50,000 more from the office of Gov. Jerry Brown and have reached out to "America's Most Wanted" for coverage.
"These two men were husbands, fathers, brothers and uncles, and it's a tragedy," said Elk Grove Mayor Jim Cooper, also a captain in the Sacramento County Sheriff's Department. "No tip is too small. Make no mistake, this was a cowardly act."
Atwal's 44-year-old son Kamaljit watched the news conference and offered this message for his father's killer or killers: "You can run, but you can't hide."
"The day will come when the suspect will be apprehended," he said.
Anyone with information about this crime is asked to call Elk Grove police at (916) 714-5115 or Crime Alert at (916) 443-HELP.
