Patrol Agent Glenn A. Phillips of the Chula Vista Station, San Diego Sector, was killed at 9:40 p.m. on July 8, 1974, in a jeep accident. He was traveling alone on the Tijuana Street Extension, a dirt road located near the international boundary approximately one mile west of the Port of Entry at San Ysidro. Agent Phillips was responding to a call for assistance from Patrol Agent Petraglia who had spotted a group of aliens entering the United States illegally.
The San Diego Police Department's report indicated that Agent Phillips was traveling at approximately 20 miles per hour, probably without lights, when his jeep crashed into the front end of a parked flatbed trailer. The jeep was badly damaged and the front of the trailer extended well into the interior and to the rear of the jeep. The bed of the trailer struck the right side of Agent Phillips' face, apparently killing him instantly.
