Search underway for 54-year-old dirt biker in Santa Clarita

Search and rescue crews are trying to locate a 54-year-old dirt bike rider who went missing overnight in Santa Clarita after calling family members to say he was traversing "treacherous trails," authorities said.

Antonio Marquez was reported missing around 10:30 p.m. Tuesday, Santa Clarita police Sgt. Jeff Curran told KTLA-TV.

His family said they hadn’t heard from him since 6:30 p.m., according to authorities.

“He did have a cell phone, that was the last contact he had with the family,” said Los Angeles County Sheriff's Deputy Joshua Dubin. “At the time he said he was on some treacherous trails, that he had to go, and that he would return. Ultimately, he has not returned yet.”

Sheriff’s deputies were unable to use the cell phone to locate the missing man's position or to make contact with him, Dubin added.

Marquez was last seen riding a red and white dual sport bike, possibly in the area of Rowher Flats or San Francisquito Canyon, Curran said.

A Los Angeles County Fire Department helicopter and a search and rescue team were deployed to search for Marquez, Curran added.
