WALKER, Mich. (WOOD) — A former Corewell Health employee is accused of embezzling hundreds of thousands of dollars’ worth of bone grafts and selling them.

According to court records, Stephen Jacobsen of Allendale confessed to the thefts and to selling the grafts and other medical supplies.

The records don’t say who was buying the stolen grafts.

Jacobsen is charged with embezzlement over $100,000 from Corewell’s warehouse in Walker, where he worked. He turned himself in on Tuesday for his arraignment in 59th District Court in Walker.

A police report obtained by Target 8 show Corewell security caught him in the act on Oct. 24 after setting up surveillance cameras in the warehouse.

“Stephen is on video carrying an empty box and entering aisle #30 where smaller boxes of bone grafts are stored,” the report states. “Stephen can be seen looking around, then removing boxes of bone grafts from the storage shelves and placing the into the larger box.”

The video then shows him taking more grafts from another aisle before loading it all into his pickup parked outside, the police report says.

Before security confronted him, Jacobsen did it again in early November, stealing another 10 bone grafts, according to the police report.

He’s accused of taking $693,000 worth of bone grafts and other medical supplies this fall alone. He later admitted it had been going on for six of seven years, according to the police report.

According to his LinkedIn page, he was a supplier performance analyst at Corewell and had worked for the health system for 15 years.

Corewell Health officials declined to comment.

Jacobsen refused to comment after the hearing.

His attorney, Clint Westbrook, told the judge that Jacobsen was a lifelong Michigan resident with no criminal history. He said he already has a new job.

Jacobsen is free on a $25,000 cash bond. He is expected back in court in December for a hearing to determine if there’s enough evidence for trial. If convicted, he could face up to 20 years in prison.
