Thornton could not be reached for comment.

Thornton was 311-97 during his career at Capistrano Valley. His teams won the Southern Section Division I-AA title in 1992 and the Division I-A championship in 1989.

Mulligan was a Cougar assistant from 1985-88. He was head coach at Escondido Orange Glen High in 1989, compiling a 9-15 record. Mulligan returned to Capistrano Valley the following season. He was an assistant at Irvine Valley College from 1992-95.
