A 39-year-old man is being held on more than $4 million bail on a string of child molestation charges.
Bay Point police said Ronald DeGuzman may have victimized more children than originally reported and are asking for the public's help.
DeGuzman is believed to have contacted his victims through churches in Central and East Contra Costa county. All of his victims so far have been boys.
Anyone with information is urged to call the Contra Costa District Attorney's office.
