Unreliable seatbelt.

From the Miami Herald:

Detective Orestes ''Oreo'' Lorenzo was driving home from a late night at work at 11:30 p.m. when he was hit by another car attempting to turn left onto Pines Boulevard from 180th Avenue.

He was thrown from his unmarked police car. It appears his seat belt tore during the accident, said Pines police spokesman David Golt.

Lorenzo was five blocks from home.
