The Bucks County District Attorney will hold a press conference Thursday afternoon to discuss the results of the investigation into the shooting death of Marie Zienkewicz.

Zienkewicz, 89, was killed in the crossfire during an alleged firefight between her neighbor and Warminster Police at the Jefferson on the Creek apartment complex in late February.

According to court documents, Zienkewicz's neighbor Andrew Cairns, fired upon police as they were responding to a call from his girlfriend, reporting that he was attempting to commit suicide.

Warminster Police Chief Michael Murphy said the responding officers returned four rounds of fire.

Murphy said that somewhere in the exchange of gunfire, Zienkewicz was hit by a bullet and died in her apartment.

The Bucks County District Attorney's Office has been investigating the incident and the results of its investigation are expected to be divulged during a press conference tomorrow at 3 p.m. 

Cairns is currently being held at the Bucks County Correctional Facility on bail of 10 million dollars. He faces several charges, including attempted murder and aggravated assault, but prosecutors have said he could face homicide charges as well, depending on the results of the investigation.

Check back with Patch Thursday afternoon for further developments.
