New Orleans Police are investigating a shooting outside of a Gentilly high school Monday (Jan. 22) that left one 14-year-old boy injured with a "superficial" abrasion wound.

Police said someone in a dark pickup truck drove by The NET Charter High School, in the 6600 block of Franklin Avenue, and fired while a group of students were in front of the school, in the parking lot. The shooting took place about 1:30 p.m., principal Elizabeth Ostberg said.

One boy was injured: While police initially said the 14-year-old had a graze wound from a bullet, NOPD later said that the boy's injury to his elbow was not consistent with a gunshot graze and was actually an abrasion.

During their investigation, police found that one of the students who had been standing with the group that was in front of the school tested positive for gunshot residue on their hands, NOPD Superintendent Michael Harrison said. Another student, who had not been with that group, was found to be in possession of live ammunition and will be arrested, Harrison said.

The school was placed on lockdown for a few hours following the shooting, but students could be seen leaving the campus at about 4:20 p.m.

Parent Kisha Jones said she was on her way to pick her daughter up from school at 3:10 p.m., when she saw police and cameras out front. She said she called her daughter, a senior at The NET, who told her they were on lockdown and weren't allowed to leave.

By 3:50 p.m., Jones was still waiting for her daughter.

"I'm just aggravated that you can't even go to work or school without something like this happening," Jones said.

Jones said she isn't as afraid as she might have been, since she was able to talk to her daughter and knows she is safe.

"But it's a scary thing to have happen at your child's school," Jones said. "You drop your child off at school and you don't except this kind of thing to happen, you expect them to be safe at school."

Another parent, Edith Scott, said she received a text from her son at 2:08 p.m. that said, "Mom, they shooting at the school. Don't call my phone, they'll take it away."

Scott said her first thought was to get to the school so she could help her son.

"I called the school first, and they said they had a situation going on and they had a lockdown going on, but that everyone was OK," Scott said.

The school told her over the phone that her son was unharmed, but said it would be awhile before the students were released.

As she was talking, her phone rang at 4:40 p.m. with a prerecorded message from the school explaining the incident. Scott said that was the first time the school contacted parents to let them know what was going on, three hours after the shooting.

"We just found out through word of mouth that there was some kind of shooting, just from what we heard from our children," Scott said.

Scott said The NET has offered many beneficial resources for her son and the shooting has not changed her opinion.

"I still want him to come because he's learning so much here. This is a great school, he's improved so much here," Scott said.

However, Scott said she hopes to see some changes to ensure nothing like this will ever happen again.

"We don't need this happening when they're in school, when they're trying to learn," Scott said.
