The family of 17-year-old Adrein Green is looking for answers after the teen was shot in the back and killed on May 5 by a homeowner in Sanford, Florida.

The case took on even more prominence when it was announced that Green's family had hired Mark O'Mara, the lawyer who represented George Zimmerman after he shot Trayvon Martin to death in 2012, CNN reported

Police said they received a 911 call around 1 a.m. on May 6 from an unnamed homeowner who said Green, who was a junior at University High School, was trying to burglarize a vehicle in a gated community in Sanford, Florida. 

In a recording of the 911 call, the person can be heard firing two shots at Green, and according to police, the teen was found dead with a bullet in his back nearby.

Sanford Police Chief Cecil Smith said at a news conference that police tried to attempt CPR on Green. Smith added that there was evidence Green did try to break into vehicles near the site of the shooting.

Assistant State Attorney Dan Faggard later said the homeowner wasn't arrested because of Florida's notorious Stand Your Ground law, the same one used to justify the killing of Martin, according to the Orlando Sentinel. The homeowner told police that he feared for his life and was only shooting to scare Green away. 

"I just busted the shots to scare him off and I saw him turn his back to the other way," the homeowner said on the recording. 

There are no other witnesses, and police have no video of Green committing any crime, but they have responded to two theft calls and an animal control call at that same home in the last year, according to local news outlet News6.

"He was only 17. He didn't deserve this," said Green's friend, Brittany Christy.

O'Mara spoke with CNN and said the homeowner's claim was questionable because Green was shot in the back.  

"They weren't shooting in fear of personal safety. In this case, it's pretty clear, in my opinion, you aren't allowed to shoot someone because they are breaking into your car," O'Mara said.

Green's family held a 25-person protest on Monday demanding more answers about the shooting. 

“I don’t know how I feel, I really don’t. Like I say justice for Adrein, that’s all I can say,” his mother Andrea Smith-Green told News6.
