Two drivers arrested following the death of an innocent Fremont woman, in a crash during a suspected illegal street race in South San Jose, have posted bail and have not been formally charged with any crime.

Emmanuel Pourmand, 21, and Joseph Anthony Inocencio, 18, both of San Jose, had been booked on charges of gross vehicular manslaughter and reckless driving causing death following the the Oct. 22 crash, which killed 20-year-old Alyson Snow on her way home from dinner with family in San Jose.

But the two have since posted bail and don't need to appear in court until Nov. 6. No charges have formally been filed against them, pending results of a police investigation.

Police now say Pourmand and Inocencio were strangers who began racing down Branham Lane about 9:45 p.m. Thursday on the spur of the moment.

"This was impromptu," said San Jose Police Lt. Robert Reinhardt, declining to elaborate.

Pourmand did not return a Facebook message today seeking comment, and the Mercury News could not immediately locate Inocencio.

Pourmand posted bail Friday and Inocencio posted bail Saturday, authorities said. Bail for both was set at $100,000.

Since they are out of custody, there is no legal requirement for them to be formally arraigned in 72 hours, said Santa Clara County District Attorney's Office spokeswoman Amy Cornell.

The extended time gives police more time to conduct their investigation.

"Not only to we have

to prove speed," Reinhardt said, "but that they were engaged in a race, and determine which car struck which car, and which car struck the trees, and all the chain of events that took place. We have to articulate all that when we go to court. All that takes time to sift through."

Police have not said what speed they believe the two were driving. But they did say a witness told them he saw a gold 2004 Nissan and a black 1997 BMW racing down Branham Lane between Pearl Avenue and Vistapark Drive.

The Nissan rammed into Snow's car, pingponging her Jetta into a tree in the center of Branham Lane near Prince Royal Place. The BMW, trailing behind, also crashed into a tree, according to police.

Strangers tried to help Snow at the scene; one even held her hand until paramedics came. But the former cheerleader at Leland High School died shortly after the crash. Her passenger, a close friend, survived.

Snow's family plans to hold her funeral service Thursday at Bridges Community Church in Fremont. Throughout the weekend, her mother, Charlene, who lives in Fremont, and father, Mark, who lives in Utah, along with other family, friends and strangers huddled at the crash site, remembering the bubbly Snow.

Mark Snow said he is angry, shocked and in disbelief at what happened. He also half-joked about what he thinks his daughter would have wanted.

"She was such a powerful girl," he said. "So strong and vibrant. If anything, she'd want me to give those guys a couple of whacks."

He described his feelings toward the drivers as "disappointed," adding that "I want them to get everything they deserve."

Still, he said it won't do him any good to dwell in hurtful feelings forever.

"You have to figure out if you can forgive," he said. "I can't at this very moment, because I'm still grieving. But I hope to be able to."
