BUTLER TWP — A 62-year-old man will stand trial on charges he held a gun to a former girlfriend's head and pistol-whipped her in 2018, leaving her with a dislocated jaw and broken cheekbone.

Arthur “Glenn” Lumley of Liberty Township in Mercer County was ordered held for court on felony firearms and assault charges during a preliminary hearing Thursday before District Judge Kevin O'Donnell.

A felon who was convicted of shooting his ex-wife in the stomach in northern Butler County 16 years ago, Lumley is being held in the Butler County Prison on $50,000 bond. He faces a new set of charges stemming from assault allegations dating back to 2018 made in an application for a protection from abuse order made by another woman this past fall.

The 56-year-old victim did not testify at Thursday's hearing. Authorities said she is scared of the defendant.

Because the victim did not immediately report what happened or seek medical treatment, the allegations only recently came to light, authorities said, after she sought — and was granted — a protection from abuse order against Lumley.

“She's concerned that at some point if he learns of the charges and then gets out, she's afraid he's going to kill her,” county Detective David Aldridge testified about what the woman told him during an interview last month at the district attorney's office.

Aldridge, who serves as the domestic violence coordinator for the DA's office, was the lone witness to testify at the hearing.

He interviewed the victim after learning of a protection from abuse order she applied for in November against Lumley. That PFA was eventually granted Dec. 10.

The woman sought the order after the defendant allegedly vandalized a recreational vehicle at her home in Butler. City police subsequently charged Lumley with felony criminal mischief in that incident. Those charges are still pending.

But in her PFA application, Aldridge said, the victim also referred to the 2018 assault.

The woman told authorities she and Lumley had been friends for about a year in 2017 before their relationship turned romantic. She recounted the defendant showed up at her then-apartment in Butler Township around Easter 2018, and became enraged during an argument.

“He had a gun held to her head and said he was going to friggin' kill her,” Aldridge testified, recalling what the woman told him.

Fearing for her safety, she tried to get away. “She alleges he pistol whipped her upside the head,” Aldridge said.

The assault, she told the detective, left her bleeding and with pain to her jaw and face. She eventually went to see her dentist in Butler.

A letter from the woman's dentist dated April 17, 2018, detailed the findings of his examination, which included a CT scan.

“The lower jaw was displaced and the range and motion was impaired,” Aldridge said, citing the letter. “There was swelling and bruising.”

The examination also found the woman suffered a left orbital fracture.

Along with the dentist's letter and pictures from the CT scan, prosecutor Robert Zanella, an assistant district attorney, presented as evidence a photograph of the victim, taken around the time of the alleged assault.

It was not immediately clear if the woman took it herself or if a friend took it. The photos showed her with bruising to the left eye and lower jaw area.

On cross-examination, Lumley's attorney, public defender Charles Nedz, tried to emphasize the lack of evidence against his client.

Aldridge, for example, acknowledged that he has not recovered the gun allegedly used in the assault.

“Have you recovered any evidence that connects Mr. Lumley to that alleged assault?” Nedz asked.

The detective noted he interviewed a longtime friend of the victim who remembered seeing her injuries and inquiring about them.

“She explained to me that the victim disclosed to her shortly after (the assault) what happened,” Aldridge said.

“Aside from (the victim's) statement and the statement of her friend,” Nedz asked Aldridge, “there is no other physical evidence that links Mr. Lumley to that crime?”

“No,” the detective replied.

Nedz, following testimony, asked O'Donnell to dismiss the most serious charges against his client, arguing insufficient evidence.

But in referring to the “totality” of all the evidence, O'Donnell ordered Lumley to be held on all counts — felony charges of aggravated assault and prohibited possession of a firearm and a misdemeanor charge of terroristic threats.

Because the defendant's criminal history includes felony convictions in Butler and Allegheny counties, he cannot possess any guns under state law.

One of his convictions in Butler County was for the Aug. 13, 2003, shooting of his ex-wife with a .22-caliber rifle during an argument at their former marital home in Cherry Township. She was hospitalized and released five days after the shooting.

The defendant in that same incident also fired a second shot at his ex-wife's mother, who also was at the house. That shot missed.

Prosecutors originally charged Lumley with top counts of attempted homicide. In 2006, he pleaded guilty, but mentally ill, to two counts of aggravated assault. He was sentenced to seven-and-a-half to 15 years in state prison followed by 10 years on probation.
