Officer charged with killing unarmed driver laying facedown

HARRISBURG, Pa. — A Pennsylvania police officer was charged Tuesday with criminal homicide after investigators concluded she shot an unarmed motorist in the back as he lay facedown after a traffic stop over an expired inspection sticker.

Authorities accused Hummelstown police Officer Lisa J. Mearkle of shooting 59-year-old David Kassick twice Feb. 2 without legal justification. She was released on $250,000 bail, her lawyer said. He planned a news conference later in the day.

Authorities said Mearkle had attempted to pull over Kassick for expired inspection and emissions stickers before he sped away. She caught up to Kassick near his sister’s home where he had been living for a short time.

He got out and ran before Mearkle incapacitated him with a stun gun, held in her left hand. He was on the ground when she shot him twice in the back with the gun in her right hand, police said.

Mearkle, 36, told investigators she fired because he would not show her his hands and she thought he was reaching into his jacket for a gun.

The offense of criminal homicide encompasses a range of charges, from misdemeanor involuntary manslaughter to felony first-degree murder. Prosecutors often narrow the charge later in the process, about the time when defendants are formally arraigned.

The stun gun recorded portions of the encounter, and District Attorney Ed Marsico called it the strongest evidence in the case.

He said it appeared Kassick had been trying to remove stun-gun probes from his back.

“At the time Officer Mearkle fires both rounds from her pistol, the video clearly depicts Kassick lying on the snow covered lawn with his face toward the ground,” according to the arrest affidavit. “Furthermore, at the time the rounds are fired nothing can be seen in either of Kassick’s hands, nor does he point or direct anything toward Officer Mearkle.”

Marsico said Mearkle waited 4 seconds between the first and second shots, and afterward performed CPR. He called the shooting “a tragedy for all involved.”

The district attorney said a syringe was found near Kassick’s body, and he had alcohol and unspecified drugs in his system when he died.

Lawyers for Kassick’s family and estate issued a statement calling the charges “a substantial step toward closure” after what they described as a horrifying tragedy. They said he had worked as a Teamsters union laborer and struggled with addiction.

“Mr. Kassick is now dead as a result of a traffic stop, a routine traffic stop,” said one of the family’s attorneys, Christopher Slusser. “He should not be dead. He should not have died as a result of that traffic stop. And the manner in which he was shot — you can infer from that what you will.”

Hummelstown Police Chief Charles M. Dowell did not respond to a message seeking comment, but his department issued a news release that said it had cooperated fully, calling the matter “an extremely difficult case for all involved.”

“We are servants of justice and must now allow the judicial process to conduct a fair and impartial review of the allegations that have been presented,” the news release stated.
