Timothy Jacoby

More than two years after Monica Schmeyer was fatally shot in her Manheim Township home, police have arrested the man they say killed her.

And York County District Attorney Tom Kearney said the investigation isn't over.

Timothy Matthew Jacoby, 39, of York County Prison, was arraigned Tuesday afternoon on charges of homicide, burglary, receiving stolen property, illegal possession of a firearm by a felon and tampering with evidence. No bail was set.

He's currently serving four to eight years in prison for a previous case in which he was charged with illegal firearm possession and receiving stolen property, officials said.

Southwestern Regional police officers responding to a 911 hang-up call found the 55-year-old Schmeyer dead in her 3414 Trone Road home about 3 p.m. March 31, 2010.

She died of a gunshot wound to the head and suffered other traumatic injuries during or prior to the attack, police have said.

Nothing appeared to have been taken from the home, located in a secluded wooded area, according to police.

The allegations: According to Jacoby's arrest affidavit, witnesses in the area saw a man fitting Jacoby's description walking toward Schmeyer's home about the time of the homicide.

Charging documents don't reveal a motive for the slaying, and officials aren't talking about what they suspect the motive might be.

"We are being close-lipped about information," Southwestern Regional Police Chief Greg Bean said, adding he is not in a position to discuss motive or other details of the case.

"We want to make sure our (allegations are) complete before we talk about it," he said.

Open case: Kearney said the investigation -- headed up by Southwestern Regional Sgt. Lisa Layden and York County Detective Doug Demangone -- is ongoing.

"Motives are always subject to continued investigation," Kearney said.

He said he's unsure whether there will be more arrests in the case but told The York Dispatch, "We never rule anyone out."

Jacoby is friends with the victim's ex-husband, 57-year-old Dr. Jon D. Schmeyer, an ophthalmologist formerly of Hanover and now of Williamsburg, Va., documents state.

At Hooter's: At the time Monica Schmeyer was killed, her husband was at Hooter's restaurant in York with friend Sara Powell, who at the time was Jacoby's fiancee, according to Jacoby's arrest affidavit.

Powell told investigators Jacoby usually accompanied them, but wasn't there that day, the affidavit states, and a former Hooter's employee confirmed previously seeing Jacoby and Jon Schmeyer together at the restaurant. Police said the men were part of a social group that frequently met at Hooter's.

Monica Schmeyer was killed with a .32-caliber bullet, fired from a .32-caliber semi-automatic gun, possibly a Kel-Tec, according to the affidavit.

Investigators found and seized two .32-caliber Kel-Tec guns last summer -- one at Jacoby's home, the other at his parents' home, police said.

Shell casings: State police ballistics experts determined a spent shell casing found at the scene of the homicide was fired from the same gun as spent .32-caliber shell casings recovered by police from the home of Jacoby's parents, the affidavit states.

Those experts also determined the interior barrels of both guns had been scraped or filed, the affidavit states, which is the basis for the evidence-tampering charge.

Investigators learned that after the homicide, Jacoby bought a new barrel for one of the Kel-Tecs, although it apparently didn't fit the weapon, according to the affidavit.

Felon: Jacoby's criminal history also includes a 2006 felony robbery conviction for a Springettsbury Township incident, police said. Because he's a convicted felon, Jacoby is prohibited from possessing firearms.

Witnesses told investigators they saw a man fitting Jacoby's description in the area of the victim's home around the time of the homicide, and one of those witnesses said Jacoby was walking along Snyder Mill Road toward a silver or gray van parked there, according to the affidavit.

Silver van: Jacoby's former employer told police he was driving a silver van the day Monica Schmeyer was killed, the affidavit states.

It's unclear whether Jacoby has retained an attorney.

Repeated calls to Jon Schmeyer's home went unanswered, and his cellphone's voice mail was not accepting messages.

"This was an extremely long and difficult case, where information came in an inch at a time," Bean said. "A lot of credit goes to Sgt. Layden and the district attorney's county detectives."
