Tyler Rosen, 18, was in a medically induced coma Tuesday, more than a week after he was struck by a hit-and-run driver. He was walking on Norco Dr. near Alhambra St. when he was hit.
Rosen underwent more surgery Tuesday.
Belinda Watson, Rosen's mother, says it was the worst phone call of her life receiving news that her son was critically injured by a hit-and-run driver.
"My poor son, and Dave's son, is laying lifeless in the hospital bed, hasn't been able to speak, doesn't move," said Watson.
It happened on Norco Dr. last Monday just after 2 p.m. Police say Rosen was walking along a horse trail when a driver veered across traffic and crashed into him. Witnesses say the driver turned around, looked at the victim and sped off.
"How this driver looked back and saw my son laying on the ground and kept on going -- that disturbs me a lot. There needs to be justice with this man that did this," said Dave Rosen, Tyler's father.
The suspect is described as a white male adult, between 18 and 25 years old.
The vehicle is a late 1990s or early 2000s dark-colored step-side truck, possibly a blue Ford F-150, perhaps missing its driver-side mirror.
Tyler Rosen is a BMX competitor who's been riding for more than 12 years. His family says he has several sponsors after winning competitions at local skate parks.
For the past week he's been confined to a hospital bed in a coma.
