Jordan Sharifi was arrested and charged with tampering with or fabricating physical evidence, theft of firearm and making a firearm accessible to a child.
The arrest is connection with the death of Raymond Howell, Jr., who was found dead last week in a ditch in a McKinney neighborhood.
Howell died from a self-inflicted gunshot wound, according to police. Howell's family has said on social media they believe bullying at school drove Howell to kill himself.
The arrest warrant affidavit obtained by FOX 4 on Monday afternoon stated Sharifi found Howell dead in a ditch after Howell's mother called him and asked if she knew where her son was.
Sharifi confessed to police he stole the gun Howell used from a family he was staying with and gave Howell multiple rounds of ammunition. He told police he gave Howell the weapon to protect himself from other teens.
Howell had recently been in two fights, Sharifi told police.
While many friends of Howell's friends took to social media claiming he was bullied, McKinney ISD has no record of bullying complaints by Howell or his parents.
The district did know of one fight Howell was involved in and said all students were disciplined, but the district did not classify it as bullying.
Sharifi also said when he found his friend dead, he took the gun and tried to throw it down a drainage tunnel so police wouldn't find it.
Sharifi's bond has been set at $300,000.
Howell's family released a statement on Monday afternoon through a family spokesperson:
"We want to thank our friends, family and the public for the outpouring of support that we have received regarding the loss of our son and brother, Raymond "Junior" Howell. Even at the tender age of 14, Raymond lived a life of love, strong values and integrity that some people never fully experience. As a family, we ask that you give us the peace, privacy and time that we need to grieve and move through this tragedy. Our hope is that it one day allows for a truly meaningful conversation … and more importantly real change for the way we treat others in our schools and throughout our communities."
Many who knew both Howell and Sharifi are stunned Sharifi could have any involvement in Howell's death.
"Honestly, if Jordan knew what was going on, I honestly believe in my heart it would've never happened," said Keeley Seward, a junior at McKinney Boyd.
Some McKinney moms are organizing a rally to end bullying Thursday and Friday outside Boyd High School.
"Clearly, the system they have in place failed this young man," said Val Martin, one of the organizers.
