In early November, 27- year old Tyrone Beamon Jr. and 21-year-old Shaundrea Milhouse were found dead in a home on Waller Road in Mount Olive.
Police believe the couple was dating.
Investigators say three children were left alone for two days with the bodies.
Monday, the Wayne County Sheriff doubled the reward to $6,000 for information into the murder.
Anyone with information is asked to call the Wayne County Sheriff's Office at (919) 731-1401.
