FULLERTON — A 44-year-old former teacher and Jehovah’s Witness church elder pleaded guilty Tuesday to sexually assaulting one of his 13-year-old students.

Jason Morris Gorski pleaded guilty to two counts of lewd acts with a minor younger than 14 and is expected to be sentenced to six years in prison on Jan. 26, defense attorney Brian Neal Gurwitz said.

Gorski was a teacher at the now-shuttered Southwestern Longview Private School in Long Beach, where he met the victim, from 2003 to 2007, according to the Orange County District Attorney’s Office. He also attended the Jehovah’s Witness Kingdom Hall, a congregation in Cypress, and was appointed to a church elder position in 2007.

He had sex with the teen at various locations in Buena Park between June 2007 and June 2008, prosecutors said.

The victim reported the sexual abuse to authorities and Gorski was arrested in June 2016.
