The mother of one of the four young people killed at a Sweet 16 birthday party said Wednesday that news of three arrests in the shooting that injured 32 people brought her some peace.

The birthday girl’s brother, 18-year-old Philstavious “Phil” Dowdell of Camp Hill, died as his sister knelt beside him begging him to keep breathing.

He and another fatal victim, 17-year-old Shaunkivia Nicole “KeKe” Smith of Dadeville, were high school seniors. Also killed were Marsiah Emmanuel “Siah” Collins, 19, of Opelika, and Corbin Dahmontrey Holston, 23, of Dadeville.

“I just feel broken to know he is not with me,” Dowdell’s mother, LaTonya Allen said. “But I do feel a little peace knowing they arrested somebody.”

The arrests were announced the same day Dowdell’s mother met with the funeral home to discuss details for his burial.

Wilson LaMar Hill Jr., 20, of Auburn, was taken into custody about 2:30 p.m. Wednesday, according to the Alabama Law Enforcement Agency. He is charged with four counts of reckless murder.

That arrest was announced hours after officials announced that two brothers, Ty Reik McCullough, 17, and Travis McCullough, 16, were charged as adults with four counts of reckless murder.

Allen said the three suspects were not invited to the party and her daughter “didn’t know them,” but they might have come with someone else as word of the party spread on social media.

Allen said she didn’t know how the shooting happened, but that she knew her son was gone once she saw him on the floor surrounded by blood. “My daughter was kneeling beside him. He was trying to say something to her but he couldn’t,” she said.

Her daughter, Alexis Dowdell, has recounted that after her brother was shot she begged him to, “stay with me, stay with me.” She recalled: “I wasn’t crying at the moment because I was trying to be strong instead of panicking. And so I said, ‘You’re going to be all right. You’re a fighter, you’re strong.’”

Phil Dowdell, a senior at Dadeville High School committed to play college football at Jacksonville State, was an “outstanding young man,” veteran coach Roger McDonald told AL.com.

“I just can’t say that enough,” he said. “Everybody loved Phil. He always had a smile on his face. He always spoke to everyone. He was the ideal kid that you want to coach. He wasn’t just a great athlete. He was a great kid. People just love him. … It’s terrible.”
