Cody Coleman, the boyfriend of deceased Oxford teen Amelia Wakefield, was charged with her murder Friday. 

A sealed indictment opened in Chenango County Court charged that Coleman, 18, shot the 16-year-old using a 16-gauge Remington pump shotgun, according to Chenango County Sheriff Ernest Cutting.

Coleman is charged with second-degree murder and is also charged with criminal use of firearm and the criminal possession of a weapon. 

"Whenever you have an incident, you investigate everything thoroughly and when stories change and don't match physical evidence, we take a step back and the case morphs into what it is," Cutting said. "In this case, it was looked at as a homicide and not an accidental."  

The grand jury indictment was issued Thursday and was opened in Chenango County Court on Friday. 

Wakefield was found dead on 136 Water St. in Smithville on May 3, according to a police report. She was taken to Lourdes Hospital for an autopsy the next day, per the report.

Wakefield was in the 11th grade at Oxford Academy and played on the school's soccer and basketball teams, according to a statement from superintendent Shawn Bissetta. 

Donations to the family can be made at gofundme.com/f/amelia-wakefield-and-family. The fundraiser has a goal of $1,000 "for funeral expenses, wake, memorials and just for the family to take time to grieve." There is also a free self-defense class being held at 11 a.m., Sunday, May 19 in Sidney, "in honor of Amelia Wakefield." 

"It is with profound sadness that I share news of the unexpected death of one our students, Amelia Wakefield, this weekend. Our deepest sympathies go out to her family, friends, classmates and teammates, coaches, teachers, and school staff, all of whom are dealing with unimaginable loss," the statement said. "She was a valued part of our school community and will be remembered always."

Coleman is being held in Chenango County Correctional Facility without bail, according to Cutting. He was arrested on May 7 on a bench warrant for a parole violation, according to a media release. According to information given by Chenango County to the Mobile Patrol cellphone application, Coleman was charged at that time with fifth-degree criminal possession of an illegal drug at that time.
