The Texas Rangers are investigating the death of a Bosque County inmate in her cell Saturday morning.

Bosque County Jail officials discovered April Troyn, 36, of Clifton, unresponsive in her cell and began emergency medical procedures. Paramedics rushed to the jail, but attempts to resuscitate Troyn were unsuccessful, according to sheriff’s office reports.

Troyn was arrested Friday on a Clifton police warrant charging her with child endangerment.

Her body was sent to the Tarrant County medical examiner’s office for autopsy, according to the Bosque County Sheriff’s Office.
