EL MONTE (CBSLA) — Authorities are looking Friday for any more possible victims of a former church volunteer and El Monte high school camp supervisor charged with inappropriately touching teenage boys.

Matthew Alejos, 27, is being held on $700,000 bail after being arrested in November and charged with six counts of committing lewd acts upon a minor, oral copulation and annoying and molesting a minor with a prior. But detectives believe he may have more victims because of his history of working with children.
