The FBI has announced a reward for anyone with information that will help investigators ascertain what happened to three North Carolina women found dead weeks apart and within a four-block radius.

The agency is offering a $30,000 reward for information about the suspicious deaths of Christina Bennett, Rhonda Jones, and Megan Oxendine in Lumberton. Per ABC News, Bennett, 32, was found inside a house on Peachtree Street on April 18 and Jones, 36, was found in a trash can outside a house on East 5th Street on the same day.

The Lumberton Police Department elicited the FBI’s help after Oxendine, 28, was found dead behind a house on East 8th Street on June 3.

The Robesonian reported that local police said their investigation has come to a halt as they don’t know how the three women died. Police also said it’s uncertain whether the women’s deaths are connected.

Local police are also tasked with locating another young woman who disappeared in the same area a few months later. The News & Observer reported that Abby Patterson, 20, was last seen getting into a brown Buick outside her mother’s Lumberton home on September 5. She was in town from Florida visiting her mother at the time of her disappearance.

In October, Captain Terry W. Parker said they’re “99 percent sure” that Patterson’s disappearance isn’t connected to Bennett, Jones, and Oxendine’s deaths, according to WNCN.

This is an ongoing investigation. The Lumberton Police Department is urging anyone who came into contact with Christina Bennett, Rhonda Jones or Megan Oxendine to call them at 910-671-3845.
