JACKSONVILLE, Fla. -

The grieving mother of a 13-year-old girl shot and killed when someone fired several shots into her Biltmore area home early Saturday morning is speaking out. Pancy Shelton hopes someone can help police find the gunman who killed her daughter and critically injured her best friend.

"All I want is justice. I want justice for these two beautiful girls," Shelton said.

Police said five people were inside when dozens of shots were fired into the mobile home on Missouri Avenue about 4:45 a.m. Saturday.

Jazmine Shelton was shot and killed while in the living room, according to police. A second shooting victim, 14-year-old Megan Simmons, was taken to UF Health Jacksonville in critical condition.

Police say they believe the family's home was targeted. Shelton believes it was drug-related and that another family member was the intended victim.

Channel 4 crime analyst Ken Jefferson visited the site Sunday and believes the shooter or shooters intended to kill. He says a high-powered weapon was used.

"You can tell by where these holes are that the person was anticipating that the people inside were going to hit the deck," Jefferson said.

Shelton spoke Saturday night with Channel 4 about the love she has for her daughter and the reality that she'll never see her again.

Jazmine Shelton "If you knew her, you would have loved her," said Shelton. "She was an amazing child. She wasn't but 13 years old and had her whole life ahead of her and it was taken from her."

Shelton said Jazmine (pictured, right) would've soon started school at Lakeshore Middle. She said she was kind and caring, and had a way with people.

"She had a good sense of humor. She would make you laugh. She has the most beautiful smile," said Shelton. "I'd love to see her smile again."

In front of the home stands a small memorial in honor of both girls. For Shelton, her thoughts are now on what she's lost, and all that she will miss.

"I will never see my daughter have kids," said Shelton. "I will never be able to see her get married, a career, learn to drive a car, all of that was taken from me."

Sheriff John Rutherford told reporters this was not a random act of violence.

"I saw dozens of bullet holes in the walls of this trailer, which shows just how violent this shooter or shooters were. This has got to stop," Rutherford said in an emotional Saturday morning news conference. "I'm angry and upset, it's hard to talk about, a 13- and 14-year-old shot in their home, when they did absolutely nothing wrong."

The sheriff is appealing to the community to come forward with information that could lead to an arrest.

"Please call us if you have any information about this crime at 904-630-0500. Even if you think it's not important, you call us, we are going to get justice for these two young girls," said Rutherford.
