A former Seattle Academy science teacher who used his school-issued laptop to view child pornography received an 18-month prison sentence on Friday.

Gabriel Cronin, 42, possessed 117 images of teens engaging in sexually explicit conduct, according to a news release from the U.S. Attorney’s Office. He used an Onion Router to find child pornography, and then deleted it afterward, Cronin told investigators, according to the federal complaint filed after his arrest last November.

Acting on a tip from Cronin’s cousin, the National Center for Missing and Exploited Children forwarded that information to the Seattle Police Department’s Internet Crimes Against Children Unit. Cronin’s cousin reportedly told investigators the former science teacher and robotics program leader is addicted, and she was compelled to report him due to his profession.

Cronin denied having engaged in any inappropriate behavior with his students during the investigation.

The Capitol Hill private school placed him on administrative leave on Nov. 20 — a day before his arrest — and fired him two days later.

“Mr. Cronin’s arrest affects our students and community on a profound level,” said Rob Phillips, Associate Head of Schools, in the Nov. 22 news release. “Our highest priority at Seattle Academy continues to be the safety and well-being of students.”

The news release states Cronin took responsibility for his actions, saying what he did was “extremely perverted and reprehensible…. My actions contributed to ongoing harm to kids…. I should have left teaching. My actions were sick and selfish.”

Cronin will have to register as a sex offender serve 10 years of supervised release when he gets out of prison.
