A U.S. Postal Service employee who stabbed a supervisor in the head at a U.S. Postal Service (USPS) facility in San Diego was convicted March 1 of assault on a federal employee.

Edwin Cuadrado Jr., 37, of San Diego stabbed a USPS supervisor on Aug. 25, 2023, in the parking lot of a USPS mail processing and distribution facility on Rancho Carmel Drive, according to a news release from the U.S. Attorney’s Office.

Court documents show that Cuadrado parked his USPS tractor trailer at a nearby gas station but was told by a supervisor that he was not allowed to do that. Cuadrado then threw something at the supervisor’s car and pushed him.

The supervisor and two other individuals confronted Cuadrado at the USPS facility to tell him that he had been put on leave.

Cuadrado then pushed the supervisor with whom he had argued before and stabbed another supervisor multiple times in the head, the U.S. Attorney’s Office said in a statement.

The victim was taken to a hospital for treatment.

Cuadrado left the scene but was arrested Aug. 30, 2023. He was ordered by U.S. Magistrate Judge William V. Gallo to be held without bond after the government argued that he was a flight risk and a danger to the community.
