Baton Rouge police in Louisiana have arrested a suspect in connection with the disappearance of Nathan Millard, a Georgia father of five and director at a construction firm who went missing from a business trip for days before he turned up dead in a vacant lot.

Early on March 7, authorities found Millard, 42, dead and reportedly rolled up in a carpet off Scenic Highway in Baton Rouge – about a seven-minute drive from where he was last seen on Feb. 23 at Happy's Irish Pub downtown with a client.

The Baton Rouge Police Department (BRPD) arrested Derrick Perkins, 45, on Monday "for his involvement in the improper disposing of Nathan Millard’s body" after initially apprehending him on March 13.

Perkins is facing charges of unlawful disposal of remains, obstruction of justice, simple criminal property damage and failure to seek assistance.
