Anthony Trevillion Tuesday testified he fired a shotgun into the Grammar Street home where 25-year-old Justin Maurice Harris died last summer, but told jurors it was a mystery man, known to him only as “Killer C” from New Orleans who fired the AK-47 that an expert witness said caused the fatal wound.

Trevillion, 30, is the first of five people, four of them brothers, who are scheduled for murder trials in the June 17 death of Harris.

“Killer C” is not a suspect and no one other than Anthony Trevillion has ever mentioned his existence, said Vicksburg Police Sgt. Sandra Williams, lead investigator, who also testified Tuesday.

The case may go to jurors in Warren County Circuit Court today.

Prosecution witnesses included Dr. Steven Hayne, state pathologist, who testified that a rifle bullet killed Harris., and Sgt. Williams, who said Trevillion’s testimony does not match the statements given by his four co-defendants, who are brothers Alonzo Trevillion, 35, Armond Trevillion, 28, and Matthew Nash, 29, and Rufus Armstrong, 32. In addition to murder, all five also face charges shooting into an occupied dwelling, two counts of aggravated assault and possessing weapons after a felony conviction.

In addition to the testimony of Anthony Trevillion, Garrod Bunch, 25, Jarvis Bowman, 22, both of whom were in the house with Harris when he was shot and killed, and Linda Miller, the woman who said she showed the Trevillions where Harris stayed just before the shooting occurred, spent time on the witness stand.

All said Anthony Trevillion and Harris both had children by the same woman and that she was Anthony Trevillion’s girlfriend at the time of the shooting.

Events leading to the shooting, the defendant testified, were at the New New Orleans Cafe, a now defunct downtown night club on Grove Street, where he hit Harris because his girlfriend told him that Harris had pushed her. Later, after he took his girlfriend home, Trevillion said he saw Harris at the Smoke Break, a convenience store at Clay and Cherry streets. Harris, unaware of Trevillion’s being there, was talking about Trevillion, making insults. However, no altercation took place at the convenience store, Trevillion noted.

Trevillion said he returned to his apartment at 1319 China St. While there, Nash asked a friend, Miller, where Harris lived and she agreed to show them. According to Trevillion, he, his brothers, Armstrong, Miller, “Killer C” and another friend from New Orleans, identified only as “Little Head,” went to the Grammar Street residence.

Trevillion said Miller first went up to the Harris’ home and talked briefly. Then the others, who parked away from the home, walked to the home with two firearms, a 12-gauge shotgun and an AK-47 assault rifle. After a brief discussion in front of the home, shots were fired.

Bunch and Bowman said they were able to find cover toward the back of the home, but Harris was hit.

Trevillion said he and the others left, then threw their weapons in the Mississippi River and went home. About four hours later, Trevillion said he was awakened by police offices who were handcuffing him.

Williams, along with Vicksburg Police Lt. Billy Brown, said Tuesday that no weapons were recovered in the river, but police found one used 12-gauge shotgun round and 19 used AK-47 rounds at the home.

Anthony Trevillion is facing murder charges a second time. Twelve years ago, he and Armond Trevillion, along with two other men, were charged and indicted on two counts of murder for the deaths of Nathan Carson Jr., 26, and Frederick Freeman, 19, who were shot to death Aug. 18, 1996, outside the former River City Cabaret at Mulberry and Levee streets. Armond was 16; Anthony, 19.

One of the other co-defendants took blame for the killing, and murder charges against the teens were dismissed. They were convicted of aggravated assault and sentenced to 15 years in prison.
