Instead of collecting parting handshakes and a gold watch, a New Jersey police officer spent his last day on the force writing out tickets for 14 patrol cars with expired inspection stickers, the Asbury Park Press reported Monday

Cpl. Frank Holden says he was just doing his job. However, that might only be half the story.

The 26-year veteran told the Asbury Park Press he retired at the end of the year because Police Chief Robert Oches is hurting morale, and that he spoke to Oches about the vehicles that needed to be inspected several months ago.

Middletown is investigating the validity of the tickets Holden wrote, Bernard Reilly, the township's attorney, told the Asbury Park Press. It is considering challenging them in court.

Holden wrote some of the tickets for police vehicles that were out of service, Reilly said, adding that Holden was "embittered."

Driving a vehicle with an expired inspection sticker may result in fines between $100 and $200.
