Jurors began deliberations at 6 p.m. Wednesday and reached a verdict around 3:30 p.m. on Thursday.
A jury convicted Inman in 2010 in this same case and sentenced him to life without the possibility of parole.
But the South Carolina Supreme Court reversed the conviction and ordered Inman a new trial last year saying the Circuit Court improperly granted a motion and committed a legal error by denying Inman his right to challenge a juror during jury selection in that 2010 trial.
After the verdict was announced Thursday, there was a scuffle between Inman, officers and a prosecutor.
Inman swung at an officer and was taken down by other officers.
His sister somehow made her way past officers to get to Inman and was arrested.
Inman then spat on Deputy Solicitor Kernard Redmond and Dillon County Sheriff Major Hulon.
A deputy received minor injuries from being cut by the handcuffs in the struggle to restrain Inman.
Deputies finally got him out of the courtroom.
They brought him back in a short time later wearing a spit guard and prison attire.
Inman apologized to the court for his actions after the verdict.
Inman's attorney Thurmond Brooker asked the court to have leniency on his client.
Circuit Court Judge Paul Burch sentenced him to 30 years in prison on the armed robbery charge.
Burch said he'll be sentenced at a later time on the other charges, including the murder charge.
Inman's sister was found in contempt of court and sentenced to 15 days in jail.
Inman and two other teenagers went to Stutts' home on August 17, 2009 asking for a drink of water.
Fourth Circuit Assistant Solicitor Shipp Daniel said during the trial earlier this week that Stutts directed the teens to the outside faucet.
"She tried to help three men with water on a hot day. And what did she get in return for that? Death, a brutal senseless death," said Daniel.
The teens hit Stutts with a gun and threw her in the trunk of her car, Daniel said.
He added they drove around in Stutts' car with her screaming for help in the trunk.
The teens turned up the volume of the radio to drown out Stutts' cries for help, Daniel said.
He said they killed her and left her body on a dirt road in Dillon County.
Inman's attorney, Thurmond Brooker, said there are no fingerprints or DNA tying Inman to the crime scene.
He said police gathered lots of evidence, including the gun used in the killing, but none of it links to Inman.
