WICHITA, Kan. (AP) — A woman who was sexually assaulted and set on fire is in critical condition Monday as police turn to the public for help in finding her assailant.

Lt. James Espinoza said Monday police have been unable to interview her at the hospital due to her medication and condition. She gave a brief description of her assailant at the scene.

Firefighters responding to a grass fire at a Wichita park found the 36-year-old woman with severe burns over 55 percent of her body and cuts on her head.

Espinosa calls it a heinous and cruel act. Officers have been contacting residents in the area. Police ask anyone who may have seen anything to contact authorities.

The attacked occurred near Wichita State University, but the victim was not a student.
