Johnston County officials say a friend went to the home on Highway 242 Wednesday morning and found the man dead.
Neighbors are stunned saying the 62-year-old victim was very well liked.
Police have two people in custody they found at a nearby migrant farm.
As soon as they get search warrants for the house and migrant housing, they say they may know more about why the man was killed.
Victim's friend James Holder could not hold back the tears when he thinks of his friend, Bobby McLamb. The two ate dinner together every night.
"He would give you the shirt off his back. If you needed help, he would help you," Holder said.
McLamb was found dead inside his home at 8:30 a.m. after he failed to show up for work at a gas and supply store.
Family and friends tell Eyewitness News he was stabbed and beaten.
Johnston county sheriff's officials went on a manhunt for two suspects at a migrant housing complex nearby.
They combed the area by foot and by car, while a highway patrol helicopter circled a wooded area near the farm.
That is where they found one suspect and took him into custody. The man, his mother and his girlfriend are charged with robbery and first degree murder.
Luis Angel Reyes Hernandez, 27, Nancy Hernandez, 48, and Amanda Jean Russell, 26. All live on Godwin Lake Road in Dunn.
The three are being held in the Johnston County Jail under no bond.
Authorities will not say what the connection is between the suspects and McLamb, but family and friends say he kept cash and weapons in his home.
"We got to be real, real close. We would hunt together. We would go places together," Holder said.
Holder and his family say their dinner table will be empty now and they will not rest until there is justice for their friend.
"He's going to be missed, he really is," Holder said.
Friends say McLamb's home has been broken into before.
The investigation is ongoing, with the possibility of additional charges.
