WREG learns new information about what led to the Zodiac Park shootings

MEMPHIS, Tenn. -- A 17-year-old boy was charged with firing into a crowd of teens in a park near the airport, killing 16-year-old Alana Tello and injuring five of her friends.

Friends of the victims said until news of his arrest, they'd never heard of Marcus Malone.

Sources close to the investigation told WREG Malone was the only person who pulled the trigger.

The victims and their family said that's not true and claim there were multiple people firing weapons, and this was a planned attack that brewed from several earlier incidents.

WREG obtained pictures of a bloody knuckle with inflammatory words under it, and another picture of Tello and a friend daring two girls to "come at us."

Sources told us the pictures were uploaded to Tello's Snapchat just before she was shot and killed Tuesday night.

WREG spoke to one of the teens who was with Tello that night.

She didn't want to go on camera, but said they drove from Horn Lake to Memphis. The plan was to fight another group of girls at Zodiac park to settle an ongoing feud.

She said they were in the parking lot about a minute when a group of guys wearing bandannas came out of the woods and opened fire shooting at least one person who was already on the ground multiple times. That victim is now paralyzed.

Tello was killed. Five others, between 16 and 21 years old, were shot.

"Get all of them justice! To get what they deserve, the ones who orchestrated it, to bring them down," said Tello's mother, Cristy.

She pleaded for justice Thursday night at a vigil.

Hours later, police arrested Malone.

A spokesperson for the Tello family told us one arrest is not enough.

They believe this was an orchestrated ambush, and there were several accomplices.

However, police sources said it doesn't appear to be premeditated. That's why Malone is charged with second degree murder.

Malone was in juvenile court Friday.

It hasn't been determined yet if he will be charged as an adult.

Police Director Michael Rallings spoke about Malone's arrest Friday afternoon.

"We've charged Marcus Malone, a 17-year-old at Whitehaven High School who should be thinking about what am I going to do the rest of my life," said Rallings. "Especially a young man at one of our finest high schools, and now his life is forever changed."

Rallings said this has become a sad reality where too many kids are resorting to violence.
