Dylan, Grandson of Michael Landon

RANCHO PALOS VERDES, Calif. (KABC) -- The daughter of the late actor Michael Landon, who is best known for his roles in hit TV shows like "Bonanza" and "Little House on the Prairie," is asking for a possible witness in the death of her son to come forward and help in the investigation.

Shawna Landon's son, 24-year-old Dylan Lupia, was struck and killed by a Los Angeles County Metro bus on Aug. 17 as he was walking in the bike lane of Palos Verde Drive South, near the Terranea Resort in Rancho Palos Verdes.

The driver of that bus, according to Shawna Landon, continued driving, only stopping about a mile and a half later to call in a report that his bus had been vandalized.

"How could you not see that you hit someone? How could you not see that you hit a human being and then just leave him on the side of the road?" said a tearful Shawna Landon. "There's no possible way he couldn't see him coming, walking towards him, and to not pull over and stop or call 911 ... It's not humane. It's unfathomable."

The Los Angeles County Sheriff's Department tells Eyewitness News it's investigating and has not ruled out a criminal case, but is still awaiting reports from the coroner's office.

what a terrible thing to happen for the Landon family I can't believe the bus driver would be so cruel as to just keep driving. I hope the family receives some peace in all of this
