ELIZABETH - Authorities say a Union County police department was deficient in disciplining a police officer who now faces drunken driving charges in a fatal crash.

The county prosecutor's office says that the Linden Police Department was deficient in disciplining Pedro Abad after he was charged twice with drunken driving before the fatal crash in March. Officials did not say what those deficiencies were.

Abad was driving a car in March that collided head-on into a tractor-trailer. Authorities say he had a blood-alcohol level of 0.24 - three-times the legal limit.

Prosecutors say Abad was drinking at a Staten Island strip club just before the crash that killed another officer and another man. Abad and another passenger were badly hurt.

Abad pleaded not guilty to charges in the crash.

The Union County Prosecutor’s Office also says that the office has assumed oversight of the Linden Police Department’s internal affairs functions.
