A Beaufort County man will spend the next 25 years in prison after pleading guilty in connection with a 2021 shooting that left two people dead at a birthday party in Seabrook.
Guilty Plea and Sentencing
Dionte Mitchell, 26, pleaded guilty Wednesday to voluntary manslaughter and possession of a weapon during the commission of a violent crime, according to the Fifteenth Circuit Solicitor’s Office.
Circuit Court Judge Michael Nettles sentenced Mitchell to 25 years for the manslaughter charge and five years for the weapon charge. The sentences will run concurrently, meaning they will be served at the same time.
Prosecutors say Mitchell must serve at least 85 percent of his sentence before becoming eligible for release. The conviction also counts as two strikes under South Carolina’s three-strikes law.
‘A Long Four Years’ for the Victim’s Family
For the family of Shania Mulligan, the sentencing brought a sense of relief after years of waiting for the case to be resolved.
“It has been a long four years,” Mulligan’s mother said, adding that the family felt they finally received justice.
While she said the sentence does not feel sufficient for the loss of two lives, she expressed gratitude that the case has reached a conclusion.
“25 years is not a long enough time for someone who took the lives of two innocent people, but we are satisfied. We’re just going to let God do the rest,” she said.
What Happened That Night
The charges stem from a Dec. 4, 2021, incident at a home in the Seabrook community, where a birthday party escalated into violence.
According to prosecutors, several hundred people were in attendance when multiple fights broke out among groups with prior conflicts. The situation quickly spiraled, leading to gunfire.
Mitchell shot Mulligan multiple times, killing her. One of the bullets fired during the shooting entered the home and struck a second victim, Flora Mae Gantt, who also died.
Arrest After Months on the Run
After the shooting, Mitchell fled the scene and remained at large for months.
Authorities eventually located and arrested him in June 2022, bringing an end to the search.
Why the Case Ended in a Plea Deal
Mitchell had been scheduled to go to trial, but prosecutors said several challenges affected the case.
Officials cited uncooperative witnesses and a dispute over whether the first victim may have been armed at the time of the shooting. Those factors contributed to the decision to resolve the case through a plea agreement.
Assistant Solicitor Brandon R. Lanier said the case presented significant evidentiary hurdles.
Second Charge Dropped
Prosecutors confirmed that a separate charge related to the death of Flora Mae Gantt was dropped.
Despite that, Mulligan’s family said they continue to support Gantt’s family as they seek their own form of justice.
Moving Forward
In the aftermath of the sentencing, Mulligan’s family said they are working to establish a foundation in her honor. The initiative aims to support other families affected by gun violence.
“This case is a senseless tragedy,” Lanier said in a statement. “A night that was supposed to be a celebration of life turned into a nightmare that involved the loss of life.”
While the legal process has concluded, families say the emotional impact will remain, even as they try to move forward.
