Employee Charged in Boss’s Killing After Complaints About Hours

Clifton Emerson Sr., 63, was arrested in Maryland hours after Mary Kelly was found dead inside a Pennsylvania auto parts business.

SWATARA TOWNSHIP, PA — A Pennsylvania auto parts employee accused of fatally stabbing his boss after recently complaining about reduced work hours and difficulty paying rent was arrested in Maryland, authorities said Tuesday night.

Clifton Emerson Sr., 63, of Harrisburg, was taken into custody by Maryland State Police after investigators identified him as the suspect in the killing of Mary Kelly at Factory Motor Parts on Bobali Drive, according to Swatara Township police and court records cited by local news organizations. Court records show Emerson was charged with first-degree murder. Police said detectives were traveling to Maryland as the investigation continued.

Swatara Township officers were dispatched to Factory Motor Parts at 1700 Bobali Drive at 7:58 a.m. Tuesday, Oct. 20, after an employee arriving for work reported suspicious activity. Officers entered the business and found an adult woman dead. Police later identified the victim as Kelly, who coworkers described as their boss. Authorities initially announced a search for a suspect before confirming at 8:50 p.m. that Emerson had been arrested in Maryland.

According to an affidavit of probable cause obtained by local news outlets, two employees who arrived for work noticed a spilled coffee cup in a hallway, damage to nearby drywall and blood leading toward Kelly’s office. One employee looked through an office window and saw Kelly on the floor. The employees then left the building and called authorities. Investigators said Kelly had suffered multiple stab wounds. More detailed descriptions of her injuries were not necessary to establish the circumstances of her death.

Investigators reported finding bloody footprints leading from the area of Kelly’s office into an adjoining warehouse. The footprints led toward a trash container where police said they recovered two blood-covered kitchen-type knives and material that appeared to be hair. Authorities have not publicly released laboratory results linking the items to Kelly or Emerson, and the allegations contained in the affidavit have not been tested in court.

Security footage and alarm records helped investigators establish a timeline, according to the affidavit. Kelly was recorded arriving at the business about 7:17 a.m., and the building’s alarm was disarmed about a minute later using her employee code. Police said a red Chevrolet SUV entered the parking lot shortly after Kelly arrived and parked near her vehicle.

A man then got out of the SUV and moved toward the building’s entrance, investigators said. Police reported that no other people were seen entering or leaving during the period under review until the man returned to the SUV and departed about 7:37 a.m. Investigators said there were no signs of forced entry and no unsecured entrances or exits that would indicate another person had entered the building during that period.

Employees told investigators that Emerson drove a red SUV matching the vehicle shown on the surveillance recording. Police said they compared information about his vehicle with the footage. Coworkers also told investigators that Emerson had worked at the business for about four years and had recently complained that he was not receiving enough work hours and did not have enough money to pay his rent.

The statements about Emerson’s hours and finances are part of the evidence investigators cited in seeking charges, but authorities have not publicly established a motive for Kelly’s killing. A workplace complaint by itself does not prove why an attack occurred, and police have not announced evidence showing that Kelly personally made decisions about Emerson’s schedule or that a dispute over hours immediately preceded her death.

Swatara Township police confirmed Tuesday night that Maryland State Police had taken Emerson into custody. The department said its detectives were traveling to Maryland as part of the continuing investigation. Information about Emerson’s return to Pennsylvania, an arraignment or future court proceedings had not been publicly confirmed as of early Wednesday.
