The Jasper County coroner has ruled the death Thursday morning of a 16-year-old girl at her home in Joplin a suicide by strangulation.

Police responded to a call at 7:13 a.m. from 3123 E. 10th St. reporting a family member's discovery of the death of Samantha Kraner. Capt. Trevor Duncan said the girl was pronounced dead at the scene.

Coroner Rob Chappel said he subsequently ruled the death a suicide. No autopsy was ordered, the coroner said.

Brandon Eggleston, principal of Joplin High School, confirmed that Kraner was a student there. He said counselors would be available to students and staff on Friday.

"We've got our crisis team involved, and we'll have additional support for kids during the day and throughout their class periods," he said. "Our thoughts are with (her) friends and family. We want to be there to support our students and our school family."

The death marks at least the fourth suicide of a local high school student since the current academic year began in August.

Joplin High School students Ty Grafton, 16, and Ivan Taylor-Cline, 15, died by suicide on Dec. 19 and Nov. 14, respectively. Carthage High School student Jordan McConnell, 16, died on Sept. 21.

Eggleston previously told the Globe that he planned to meet with students, counselors, principals and parents this semester to develop a better approach to suicide prevention and awareness.
