LIBERAL–Authorities are asking the public’s help as they investigate the death of a southwest Kansas woman.

The High Plains Daily Leader reports 23-year-old Yesenia Rodriguez was found dead Sunday morning in the driveway of her home just outside Liberal.

Seward County Sheriff Bill McBryde says an autopsy performed Monday showed no signs of trauma. But authorities are treating the case as a homicide as they wait on a toxicology report.

According to McBryde, the woman’s last known contact was with her roommate at 3 a.m. Her body was found outside her home slightly more than five hours later.

The sheriff says Rodriguez’s car – a gray 1994 Toyota Corolla – which was missing, was found about mid-morning Tuesday in Tyrone, Okla.   McBryde also says law enforcement is looking for a man who may have valuable information.
