After getting Webb’s driver’s license, registration and insurance information, Mack and Sisca left her with a warning to slow down. Sources tell FOX 29 the entire stop was caught on their dashboard camera and that the interaction lasted less than one minute. 

Police said a man later identified as 28-year-old Reyes Rivera Oliveras of Allentown was reported walking in the southbound lanes of I-95 near the sports stadiums in south Philadelphia early Monday. Mack and Sisca were trying to get him off the road when a vehicle "traveling at a high rate of speed" struck all three, police said. All were pronounced dead at the scene, where Webb was arrested.

In a Jan. 15 tweet, Webb appeared to boast about being able to drive while intoxicated. 

"If you ask me, I’m the best drunk driver ever," the post reads.
