• A Florida teen has been charged with second-degree murder in connection to a fatal Halloween weekend mass shooting in Tampa's Ybor City.
  • The teen is also facing charges of attempted aggravated battery and attempted murder related to the shooting
  • Tyrell Stephen Phillips, 22, was also arrested and charged with second-degree murder with a firearm for the killing of 14-year-old Elijah Wilson during the same incident.

A 14-year-old boy has been charged with second-degree murder in the death of a 20-year-old during a Halloween weekend mass shooting that left two people dead and 16 injured in Tampa's Ybor City, officials said.

"This defendant is a perfect example of why we must take a strong stance against juvenile gun violence in our community," Hillsborough State Attorney Suzy Lopez said during a Wednesday night news conference announcing the charges.

The teen is also charged with attempted aggravated battery and attempted murder in connection to the shooting, Tampa Police Chief Lee Bercaw said. He said bullets and shell casings connected the teen to the 20-year-old victim, Harrison Boonstoppel.

The shooting happened after an argument broke out between two groups in the early morning hours of Oct. 29 as people were celebrating Halloween in one of Tampa’s entertainment districts.

Later that day, detectives arrested Tyrell Stephen Phillips, 22, who was charged with second-degree murder with a firearm. He is accused of killing 14-year-old Elijah Wilson.

A judge last week ordered Phillips to remain in jail until his trial. During that hearing, the man's father, also named Terrell Phillips, told the judge the shooting was in self-defense and asked that he be released from jail, WFLA reported.

"My son is righteous and he’s responsible and he’s accountable and he has an incredible amount of integrity," Terrell Phillips said.

The man's attorney, David Parry, said during the hearing that the younger Phillips fired because he thought someone in the other group reached for a gun, the Tampa Bay Times reported.

The prosecutor suggested that the teenager charged with the murder of Boonstoppel, who the AP is not naming due to his age, had a previous criminal record. He will be charged as an adult, which is allowed under Florida law for many violent and non-violent felonies.

"He’s no stranger to the juvenile justice system, but he will no longer be treated like a juvenile," Lopez said.

Police are searching for other suspects. Neither the teen nor Phillips have been charged with any of the other shootings that happened that night.

Boonstoppel's mother spoke about her son during Wednesday's news conference.

"I have been the mother of mothers watching over him my whole life," Brucie Boonstoppel told reporters. "This is just senseless and we have to do something as a community to make it better for everybody, and I plan on doing that."
