For immediate release: Suspect Arrested for Aggravated Child Sexually Abusive Activity
On July 27, 2026, Detectives from the Auburn Hills Police Department investigated an embezzlement case involving a FANUC employee. During the investigation, it was found that the employee, David Christopher Grosh, a 27-year-old Wixom resident, was taking electronic parts from FANUC and selling them online. The Detectives suspected that Grosh was photographing the stolen parts and selling them on eBay. Detectives obtained a search warrant for the employee’s cell phone to retrieve photographs of the stolen items. The cell phone was sent to the Oakland County Sheriff’s Computer Crimes Lab for analysis.
On September 9, 2026, the Lab contacted our Detective regarding the photographs and advised that they had found a large amount of Child Sexually Abusive Material on the cell phone. An additional search warrant was obtained and executed at Grosh’s home in Wixom, where investigators collected more electronics and sent them to the Lab.
Based on the evidence already obtained, the case was sent to the Oakland County Prosecutor’s Office for review of charges. On September 24, 2026, the Oakland County Prosecutor’s Office issued six felony charges. They issued 3 counts of Aggravated Child Sexually Abusive Activity, each a felony. If convicted, Grosh faces up to 25 years in prison and/or a $125,000 fine for each count. The Prosecutor’s Office also issued 3 counts of Using a Computer to Commit a Crime, each a felony. If convicted, Grosh faces up to 20 years in prison and/or a $20,000 fine for each count.
On September 26, 2026, members of the Oakland County Sheriff's Office Felony Apprehension Team arrested Grosh at this home in Wixom. The Oakland County Jail held him pending arraignment.
On September 28, 2026, Grosh was arraigned before Magistrate Melinda Balian at the 52-3 District Court. The court set bond at $500,000, with 10% cash or surety allowed. Grosh remains in custody at the Oakland County Jail. His next court hearing is on October 6, 2026, before Judge Polizzi.
