Pleasanton police have been working on this case non-stop and say they are following up on some very promising leads. The victim is a 51-year-old man, husband and father of two.
"These people that did this, they just drove away and left him," said Agnes Lamont, the victim's wife.
Lamont found her husband, David, lying on the ground unconscious just after midnight Saturday. He had gone outside to confront a group of people making loud noises outside his home. Pleasanton police believe teenagers are responsible for attacking him. Witnesses reported hearing voices of boys and girls.
"I cannot describe it. It is devastating. We have a very good man that did nothing to deserve anything bad happening to him," said Lamont.
David remains in a coma at Eden Medical Center in Castro Valley. He's suffering from major head injuries. Pleasanton police say they've been following several leads which include a vehicle description.
"We have one SUV that was seen leaving the scene by one of the witnesses. I believe it was a brown SUV," said Pleasanton Police Lt. Scott Rohovit.
Neighbors are hoping for an arrest soon. They say teenagers often hang out on the hill above the cul de sac, but never has their presence led to something so tragic.
"There's simply no excuse once an event like that happens to just simply drive away and leave a man lying in the street like that. It's just horrible," said neighbor Bob DeFeo.
Pleasanton police say they will update the public Tuesday morning with the latest on the investigation.
