LOWER MACUNGIE TWP., Pa. -

Law enforcement authorities said they have identified a person of interest in the killing of a woman who was found shot in the driveway of her home in Lower Macungie Township, Lehigh County, early Tuesday morning.

Officials declined Friday to publicly identify that person, and charges have not been filed, but state police said they do not consider Stephanie Roof's live-in-boyfriend or her estranged husband persons of interest. They told 69 News that both men have been accounted for and are cooperating with the investigation.

Recently obtained court records give a glimpse at what investigators were looking for when they served two search warrants earlier this week. A warrant was served on Roof's Toyota SUV and her home.

Investigators were interested in GPS-tracking information, DNA, blood stains, documents, weapons and other items, according to court papers.

Those records indicate that Roof's live-in-boyfriend found her shot and bleeding in her driveway early Tuesday morning and tried to perform CPR. Roof, 46, suffered a single bullet wound to her chest and died at a hospital a short time later, officials said.

According to the search warrant application, Roof's boyfriend said she typically arrived home from her swing-shift job at R&D Interconnected Solutions about a half-hour after ending her work day. Roof's boss told 69 News she usually left around 11:45 p.m.

Roof's boyfriend told investigators he fell asleep with the Pinecrest Lane home's security system turned on, but when we awoke after midnight, he realized the system had been shut off. Investigators, though, said they do not believe Roof's killer tried to get into the home.

69 News has also reviewed an inventory of items taken as a result of the two returned search warrants. Items include greeting cards, cell phones, divorce documents and a handgun. Detectives told 69 News the handgun belonged to Roof, and they do not believe it was used in her killing.

Detectives also took a piece of Roof's garage. According to investigators, it's believed the projectile may have struck the garage.

According to officials, another search warrant is still under seal, so it's unclear what information detectives were seeking in that application.

When asked if Roof's killing could center around a love interest, a detective responded "possibly."

Investigators are also looking into an unsolved arson at Roof's home. They would not comment further on a possible motive, but added they do not believe the public is in any danger and that the fire is concerning.

Roof was active with her church's youth ministry and home-schooled two of her children.
