SANTA ANA (CBSLA.com) — Authorities asked Friday for the public’s help in identifying any other potential victims of a former Mrs. Orange County suspected of using a 4-year-old relative to make child pornography and sell it to a Marine stationed in Southern California.

Meghan Breanna Alt, 25, of Irvine, was charged Friday with a count of possession and control of child pornography and three counts of lewd acts on a child younger than 14, all felonies. She also faces a sentencing enhancement allegation of substantial sexual conduct with a child.

Alt, who is being held on $100,000 bail, is scheduled to make her first court appearance Friday.

The former Mrs. Orange County, who was under surveillance, was arrested following a traffic stop in San Diego County Wednesday, Orange County sheriff’s Lt. Jeff Hallock said.

The Naval Criminal Investigative Service had alerted a regional child exploitation task force about the child pornography, leading investigators to Alt, Hallock said.

Alt is accused of sending sexually explicit images of the 4-year-old girl, a relative, to the Marine in exchange for cash and gifts. She is also suspected of advertising unspecified services online that led to her having sex with clients in exchange for money with her children present, according to Hallock.

Alt won the Mrs. Orange County pageant last year and competed in the Mrs. California contest in June of 2014. She is also involved in the Church of Jesus Christ of Latter-Day Saints in San Clemente and Irvine, where investigators believe she worked with young children as a volunteer, Hallock said.
