Woman Accused Of Killing Bristol State Trooper While DUI Posts Bail

PHILADELPHIA — A woman accused of striking and killing two Pennsylvania State Police troopers —one was from Bristol —and a pedestrian is free on bail.

Court records show Jayana Webb, 22, of Eagleville, posted 10 percent of $600,000 bail Wednesday in Philadelphia.

Webb is charged with murder, homicide by vehicle while DUI, second-degree manslaughter of law enforcement officers, and other crimes in connection with the March 21 incident on Interstate 95.

Killed were Troopers Branden Sisca, 29 and Martin Mack III, 33, as well as pedestrian Reyes Rivera Oliveras, 28, of Allentown.

Mack, a Bristol resident, left behind a wife and two children.

Mack enlisted in the Pennsylvania State Police in November 2014 and graduated as a member of the 141st cadet class.

Webb is scheduled for a pre-trial conference on Sept. 21, court documents show.

On March 21, Mack and Sisca pulled Webb over for speeding and were with her for less than a minute before they were dispatched to another part of the highway near the Philadelphia sports complexes for a report of a pedestrian on the road.

Mack and Sisca found the man, identified as Oliveras, when they arrived.

When they were trying to get Oliveras into their vehicle, another vehicle sped up to the scene and struck the three, sending Mack and Sisca over the median and onto the northbound lanes of I-95.
When backup arrived, troopers found witnesses giving CPR to the victims, but they were pronounced dead at the scene.

Authorities said Webb remained at the scene after the crash.

Both troopers spent their entire careers assigned to the Patrol Section of Troop K, Philadelphia.

Sisca enlisted in the Pennsylvania State Police in February 2021 and graduated as a member of the 161st cadet class.

Sisca, who served as the chief of the Trappe Fire Company No. 1 in Trappe Borough, is the son of Craig Sisca, a 10-year member of the Montgomery County Sheriff's Office. He's survived by his wife, who is expecting a child.

Patch previously spoke with members of the Trapper Fire Co. who continue to mourn their chief's loss.

Sisca had only just graduated from the Pennsylvania State Police Academy last August, and he made fire chief at the volunteer department in January. He just got married last September.
