The Middletown Township Police are making headway in their investigation into a fatal hit-and-run on Route 1 Monday morning near Neshaminy High School. Officers are checking several vehicles which may be directly involved.

Alexandra Ridgway, 29, was hit by multiple vehicles and none stopped at the scene. The incident forced authorities to close Route 1 north of Old Lincoln Highway in Bensalem for several hours.

Middletown Chief Joe Bartorilla confirmed they now have three vehicles in custody and are examining them. They are a Ford F-550 flatbed tow truck, a Dodge Caravan mini-van and a VW Passat.

Bartorilla says all three vehicles were at the scene. But current evidence shows none were the first to hit Ridgway.

“Based upon the roadway evidence and the catastrophic injuries sustained by the pedestrian we believe we are looking for a large vehicle, most likely a large truck or tractor-trailer unit, as the initial striking vehicle.”

The public has sent many tips to police, according to Bartorilla. Investigators are following up on all leads.

So far, Middletown crash investigators have inspected other vehicles in Bensalem Township, Falls Township, and Philadelphia. Police have cleared these drivers and owners of involvement, but are speaking to them as potential witnesses. They include two Mack tri-axle dump trucks, a Jeep Wrangler and a Mazda coupe.

Bartorilla also addressed reports of an arm found in Philadelphia several hours after the hit-and-run. He confirmed the Philadelphia Police Department is looking into the matter.

“As of now this human limb has not been positively identified and it remains unknown if it is involved in the pedestrian crash from Route 1.”

Authorities say Ridgway was standing upright when a vehicle hit her. Ridgway’s family has set up a Go Fund Me page to help cover funeral expenses. It has raised $11,238 as of Wednesday morning, more than double its $5,000 goal.

The Middletown Township Police are asking anyone with information to come forward. People can contact Ofc. Timothy King or Sgt. Michael Lubold at 215-750-3800.
