(WNCT/WNCN) – A North Carolina man is now in custody on murder charges after deputies said he killed his neighbor and a married couple in separate but "related" shootings over the weekend. According to the Pitt County Sheriff's Office, detectives arrested 55-year-old David Lever on "three open counts of murder" after law enforcement found three people shot dead on Friday in Greenville, which is about 85 miles east of Raleigh. The investigation spanned across four different crime scenes, the sheriff's office said. "As a result of interviews and evidence collected at each scene, the preliminary investigation reveals the incidents are related," according to a Saturday news release from the Pitt County Sheriff's Office. "However, this is an active investigation." A person of interest, later identified as Lever, was detained at one of the scenes before his eventual arrest, and additional charges are currently pending, deputies said.
