A California high school teacher has been arrested after investigators allegedly discovered more than 65,000 images of child sexual abuse material on a computer inside his home.
Nickolas Turpen-Arends, 40, a culinary arts teacher at Lincoln High School in Stockton, was taken into custody Sept. 22 following a months-long investigation by the California Highway Patrol.
According to CHP, investigators had been tracking an internet protocol address for months before connecting it to Turpen-Arends’ residence.
The investigation eventually led authorities to serve a search warrant at his Stockton home.
CHP’s Special Weapons and Tactics team assisted with the operation.
Investigators then conducted a preliminary forensic examination of a desktop computer found inside the home.
What they allegedly discovered was staggering.
Authorities say the computer contained more than 65,000 images depicting child sexual abuse.
The device was seized and is now undergoing a much more extensive forensic examination as investigators search for additional evidence.
Turpen-Arends was booked into the San Joaquin County Jail on suspicion of possessing child sexual abuse material.
He was later released after posting $20,000 bail and promising to appear in court.
The arrest has stunned members of the Lincoln High School community.
Turpen-Arends was in his second year working for the Lincoln Unified School District and taught culinary arts at the high school.
He was reportedly known to many students as “Chef T.”
Former student Ava Koster told KCRA that she and other students often spent lunch inside his classroom and described him as someone students felt comfortable talking to.
She said students were “drawn” to him and that learning of the allegations was alarming.
The school district moved quickly after the arrest.
Turpen-Arends was placed on administrative leave, and district officials said they are cooperating with investigators.
The district also stressed that it is currently unaware of any allegation involving a district student.
“To date, the District is not aware of any allegation and has no information suggesting that any District student is involved,” Lincoln Unified said in a statement.
Because the case remains an active investigation and involves a confidential personnel matter, the district said it would not comment further.
Investigators have also asked anyone with additional information about the case to contact the California Highway Patrol.
CHP Captain Melissa Kittell praised the agency’s computer crimes investigators for the months of work that led to the arrest.
“Our computer crimes investigators are essential to protecting innocent victims and ensuring offenders are held accountable,” Kittell said.
Turpen-Arends also has a lengthy military background.
KCRA reported that he served in the U.S. Navy from 2005 until retiring in January 2022 and worked as a chief culinary specialist before becoming a teacher.
For now, the investigation is far from over.
CHP investigators are still conducting a comprehensive examination of the computer seized from Turpen-Arends’ home, which could reveal additional evidence about the files, how they were obtained and whether anyone else was involved.
