MONROE, N.C. -- Two women face charges related to what police are calling a "suicide pact" that left one woman dead and the two suspects injured.

Monroe police arrested Linda Maples, 26, as she was released from the hospital. Maples was taken into custody Thursday just before 6 a.m. in her hospital gown.

Maples faces felony conspiracy to commit murder and murder charges after police said an apparent suicide pact fell apart Wednesday afternoon.

Police also plan to charge Jennifer McCord, 23, with felony conspiracy to commit murder, attempted first-degree murder and murder in the death of her mother, Debbie Gibson, 44.

Police Chief Debra Duncan said, "I think they decided they were going to kill themselves, and then they lost their nerve and they were going to shoot each other."

Officers said they believe Gibson shot McCord in the shoulder, McCord shot Maples in the arm and then Maples shot Gibson in the torso.

Police said Gibson was found dead in a bedroom in a home on Oglethorpe Lane, which is in the Savannah Way neighborhood. McCord was found in the garage and the other shooting victim, Maples, called 911 and was standing in the driveway when police arrived. Police said both survivors were taken to Carolinas Medical Center-Union with non-life-threatening injuries.

McCord is currently at Carolinas Medical Center in Charlotte for surgery.

Duncan said they compared evidence found in the home to the two women's statements and believe they're telling the truth.

"We have evidence we're looking at in the house. We've got statements -- what they had to say. And we're looking to see if the evidence fits the statements," Duncan said.

Neighbors like Bob Baxley said the bizarre crime is hard to understand.

"We very seldom have police come through the neighborhood," he said. "It's a very quiet neighborhood, it's very well-kept and we don't normally have concern like this."

However, Eyewitness News has learned that police were called to the home in the past for domestic violence problems between Gibson and her husband, who no longer lives in the home.

Investigators also said all three women knew they were under investigation for prescription drug fraud in Monroe and two of them had similar charges in Mecklenburg County. In Mecklenburg County, Maples was arrested five times since December 2006 on charges of driving while impaired, obtaining a controlled substance by fraud, uttering a forged instrument and common law forgery. McCord was arrested twice on charges of selling and delivering a controlled substance and obtaining a controlled substance by fraud or forgery.

Police said the women planned to commit suicide earlier Wednesday and even tested the gun used in the crime in the back yard to make sure it would work. Duncan said their primary concern is finding out exactly why there was a suicide pact.

"I don't know what happened that caused this today. I don't know if they were overwhelmed or thought that life wasn't worth living," she said.

Police said there was no evidence found at the scene that drugs or alcohol was involved in the scheme. They said they also don’t know if the prescription drug fraud investigation had anything to do with it.

Investigators said Gibson’s estranged husband, who the woman had asked for a domestic violence protection order against in the last several weeks, appears to have had no knowledge of the plan and he was nowhere near the scene when it happened.

Police plan to question the survivors again once McCord has been released from the hospital.
