Another man is in jail in Laurel for the May 6 murder of Eric Trotter.
Kevin Clark, 22, of Shubuta turned himself into to authorities late Tuesday.
Also in custody are 24-year-old Kevin and 26-year-old Travis Palmer, both of Laurel; and 19-year-old Marshall Strickland of Vossburg.
Authorities are still looking for 20-year-old Malcolm Davis of Meridian.
Trotter, 30, was found dead in the front yard of his East 10th Street home. He had been shot in the back of the head and the lower back.
Authorities say the shooting apparently stemmed from an argument the night before at a Heidelberg nightclub.
