Officials are asking for the public's help in identifying a person of interest wanted in connection with the killing of a therapist found wrapped in a tarp on a Louisiana highway.

The Tangipahoa Parish Sheriff's Office reported that William Nicholas Abraham, 69, was found dead over the weekend on a road in the community on the state's southeastern border.

Abraham's body was found Sunday morning by a passerby along Highway 51 between the unincorporated community of Fluker and the village of Tangipahoa – about 60 miles northeast of Baton Rouge, where investigators say he worked.

Abraham's body was found wrapped in a tarp, and the local medical examiner's office determined he died as a result of blunt force trauma and classified his death as a homicide, the sheriff's office wrote in a news release.
