LINCOLN, Neb. (AP) — Police have arrested two men suspected of killing a Lincoln man reported missing by his family.

One was booked into Lancaster County Jail on suspicion of second-degree murder. The other was booked on suspicion of aiding and abetting murder. Court records don’t show that they’ve been formally charged. Police say the two have been in custody since Jan. 12 on drug charges.

Police say the two are suspected in the disappearance and slaying of 35-year-old Phillip Madlock. His family reported him missing July 10.

Investigators say the two men had been looking to collect a drug debt from Madlock. Investigators think he was killed in Lincoln and his body dumped outside Lancaster County.

Police Capt. Danny Reitan declined to say Tuesday whether the body’s been found.
