MEMPHIS, Tenn. — The man Millington Police say is responsible for the death of a 15-year-old girl stood before a judge on Tuesday. 18-year-old Seth Walls has been charged with reckless homicide and reckless endangerment with a deadly weapon

WREG was there for his court appearance and learned he’s facing additional charges for another crime.

Walls has been charged in connection with the death of 15-year-old Haley Reedy. Newly released court documents say on September 11, Reedy was found dead inside Walls’s home on Clear Creek drive with a gunshot to the head.

Initially, Walls told investigators he, Reedy, and another teen were sitting on a couch playing with his gun. Reports say he told officers he left the gun on the couch and walked out of the room.

While away, he says he heard a gunshot and came back to see Reedy laying on the floor.

However, an autopsy revealed Reedy was shot in the back of the head from above. Detectives say they determined Walls was the one who fired the fatal shot.

A warrant was later issued for his arrest.

Walls’ attorney, Brandon Hall, said he plans on fighting those accusations.

“We’ve entered a plea of not guilty. The only thing that we could comment on right now is that there is a young lady that is deceased, and we do feel for her family. But at the same time, we’re going to be fighting for my client’s rights,” Hall said.

We’ve learned this was not Walls first time standing before a judge. In fact, he stood before a judge just a few weeks ago for another incident that happened in August.

According to court documents, the teen told officers two weeks before the murder, Walls picked her up from her home and brought her to his house. She says she met him on Snapchat.

Reports say once inside the house, Walls told the teen he, “killed his ex-girlfriend in this house”.

She says he allegedly pointed a gun at her and at one point placed a knife on her back. Documents state Walls eventually took the teen home unharmed. He has been charged with two counts of aggravated assault in that case.

Wall’s attorney would not comment on those allegations.

Walls was given a $10,000 bond for the reckless homicide and a $5,000 bond for the aggravated assault. He is now out on bond.

He is due back in court for both cases on October 18.
