Tristyn died of "force trauma by stabbing" and her cause of death was ruled by the medical examiner as a homicide, the St. Johns County Sheriff's Office announced on Tuesday. "We will continue to investigate this case fully and will begin transitioning this case to the State's Attorney Office," the sheriff's office said in a statement. In an interview with local news outlet WJXT, Sheriff Robert Hardwick described Tristyn's death as a "cold-blooded murder." "That being said, I don't wanna mention the number of times [Tristyn was stabbed], but it is horrific. It is horrible," Hardwick said. "And the word accident is nowhere involved in this case."

Tristyn was last seen shortly after midnight on Sunday in her Durbin Crossing neighborhood. She was found dead in a remote wooded area at about 6 p.m. by a local resident after authorities had put out a missing person alert. A 14-year-old suspect — whom PEOPLE is not identifying because he is a minor — was arrested this week in connection to Tristyn's death, Hardwick announced during a press conference on Monday. The teen suspect is currently being held on one count of second-degree murder by the Department of Juvenile Justice. "That's actually a decision we made collectively ... with the State Attorney's Office," Hardwick said at the time. "We can always increase the charge." A spokesperson for the 7th Circuit State Attorney's Office tells PEOPLE that the office has not yet determined if he will be charged as an adult.
