Inmate found dead at Henderson jail was ex-CCSD teacher, coach

A Clark County high school teacher who lost his job — twice — after theft charges and drug problems was found dead in the Henderson Detention Center on Sunday.

Henderson police called 55-year-old John Mannion’s death an apparent suicide. He was found in his cell with a bed sheet wrapped around his neck, city officials reported.

Attempts to revive Mannion were not successful.

Mannion had been fired from the Clark County school district after a 2009 arrest on theft charges. He was a teacher and football coach at Coronado High School until he was accused of stealing $17,000 in booster donations.

His criminal charges were dropped in 2011 and he fought to work at the school district again. But soon after, he was arrested again after police said he sold prescription painkillers to an undercover Las Vegas police officer.

Attorney William Terry said he represented Mannion in felony methamphetamine possession cases that resulted in a three-year probation sentence in January.

Mannion was arrested Oct. 16 by Boulder City police on a DUI charge and booked into the Henderson Detention Center.

On Oct. 17, a probation violation report was filed on his Sept. 2013 court case.
