Authorities said 18-year-old Barry Marquez Partee of Monroe turned himself in around midnight Thursday.
Partee and two others, 18-year-old J.J. Blackwell and 21-year-old Corey Butler, are accused of attacking C.F. Ewing and his wife, Epsie, at their home on May 21.
The husband answered the door and three told him they were interested in buying his truck. Police said they then rushed into the home, robbed and beat the couple and left with a small amount of cash.
C.F. Ewing has been released from a hospital but his wife remains in intensive care in critical condition.
