Dontae Harvey surrendered to U.S. marshals at 7:30 p.m. Monday at a residence in Jackson. Supervisory inspector Rick Griffin said in a statement that marshals developed information on his whereabouts and gained cooperation from his family. Harvey was being held at the Raymond detention center and awaiting transport to Starkville, Griffin said.
Mason Perry Jones, 21, of Jackson was arrested Sunday and charged Monday with capital murder in the case.
The possible motive in the killing "will come once the investigation is complete," said Bill Kibler, vice president of student affairs. "Police do have some clues but nothing that is releasable information."
MSU spokeswoman Maridith Geuder said the underlying charge that kicks in the capital murder charge is the sale of a controlled substance. She didn't elaborate on the charges.
She said Jones, who wasn't an MSU student, has requested an attorney.
A 1997 law passed in the wake of the Pearl High School shooting also makes a homicide on educational property a capital crime.
Sanderson, who had transferred from Holmes Community College, was shot multiple times outside a dorm room on the first floor of Evans Hall.
Kibler said Sanderson lived in Rice Hall, not Evans Hall. When asked why Sanderson was in Evans Hall on the night of the shooting, Kibler said he was "probably visiting."
The U.S. Marshal's Fugitive Task Force arrested Jones on Sunday in Memphis, Tenn., on an unrelated, outstanding robbery warrant from Jackson. Griffin said Jones was traveling north on a bus from Jackson under an assumed name.
Marshals were acting on a tip when they arrested him after the bus stopped in Memphis. Griffin said he wasn't sure if Jones had planned to travel beyond there.
Geuder has previously said police received a call about the shooting at Evans Hall around 10 p.m. Saturday and police were on the scene within a minute. Sanderson was taken to Oktibbeha County Hospital, where he died.
Three men fled the building in a blue Crown Victoria, officials said.
The four-story Evans Hall holds about 300 male students and is located on the north side of campus. The campus of about 20,000 students is located in a rural area in the northeastern part of the state, about 125 miles northeast of Jackson.
