Fallen State Troopers To Be Honored At MADD Walk In Philadelphia

PHILADELPHIA — A walk in Philadelphia will honor the late Pennsylvania State Troopers who were struck and killed on Interstate 95 earlier this year.

Walk Like MADD (Mothers Against Drunk Driving) is hosting a walk at 9:30 a.m. Sunday, Sept. 18 at the Philadelphia Zoo, and participants can sign up to honor Troopers Branden Sisca and Martin Mack III, who were killed by a driver authorities allege was impaired on Interstate 95 in March this year.

Registration to support Troop K, where Sisca and Mack were stationed, at the walk is available online here, and also available at 8 a.m. the morning of the event. Registration closes at 5 p.m. Friday.

The opening ceremony is scheduled for 9 a.m. and the walk is set to kick off at 9:30 a.m.

Members of Pennsylvania State Police Troop K will be participating in the walk.

The walk is about 3.1 miles.

Troop K has raised $580 out of a $5,000 goal for MADD with their team.

Mack, 33, and Sisca, 29, as well as Reyes Rivera Oliveras, 28, of Allentown, were struck by a driver at about 12:45 a.m. Monday, March 21 on Interstate 95 south, just before the Philadelphia sports complexes.

Jayana Tae Webb, 22, of Eagleville, is charged with third-degree murder in connection with their deaths.

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.

Mack enlisted in the Pennsylvania State Police in November 2014 and graduated as a member of the 141st cadet class. Sisca enlisted in the Pennsylvania State Police in February 2021 and graduated as a member of the 161st cadet class.

Both troopers spent their entire careers assigned to the Patrol Section of Troop K, Philadelphia.
Mack, a resident of Bristol in Bucks County, left behind a wife and two children.

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.
