A 17-year-old who investigators say was fatally stabbed by his teenage friend is being remembered as a gregarious high school sports star who loved to joke with friends.

Ray Castellanos was Jeremy Sanchez's wrestling coach at South El Monte High School. He says the teenager was a "very respectful, outgoing kid."

Castellanos says Sanchez was on the school's varsity wrestling team and also dedicated to his classwork.

He says he visited Sanchez's father Thursday, whom he had also coached, and the two hugged for several minutes.

Los Angeles County sheriff's detectives say Sanchez's 16-year-old friend stabbed him multiple times and left his body in a wooded area near a riverbed. Detectives are still trying to identify a motive.

They said the suspect was in a search party looking for Sanchez when he led the group to his body.
