WICHITA, Kan. (AP) — Police say a woman who was sexually assaulted and set on fire in a Wichita park is in critical condition.

Lt. James Espinoza said Monday that police have been unable to interview her at the hospital due to her medication and condition.

Firefighters responding to a grass fire at the park Friday night found the 36-year-old woman with severe burns to 55 percent of her body and cuts on her head. Espinosa calls it a heinous and cruel act.

No one has been arrested. Espinoza says the woman gave a brief description of her assailant at the scene.

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

Police have been contacting area residents and are asking for witnesses to contact authorities.
