A now-former Florida police officer watching pornography on his cellphone slammed into another vehicle that had stopped for a school bus flashing its light.

According to an internal investigation report obtained by the Smoking Gun on Friday, 28-year-old Lake County Deputy Sheriff Tristan Macomber rear-ended a 63-year-old woman’s Toyota Corolla, then claimed his brakes malfunctioned.

When investigators discovered that Macomber’s bodycam footage showed him operating a cellphone in the moments before the crash, the officer said he’d been texting with colleagues.
