Motive still 'up in the air' in mysterious shooting of pregnant Ohio woman, toddler

The mystery surrounding the shooting death of a pregnant Ohio woman and the wounding of her toddler is deepening.

A sheriff's office in rural southern Ohio held a news conference Thursday in which authorities released few details about the investigation. Brown County Sheriff Dwayne Wenninger (WIN'-in-jer) says the motive "is still up in the air."

Authorities have made no arrests in the Aug. 28 killing of 22-year-old Brittany Stykes. She was five months pregnant, and the fetus didn't survive. Stykes' 14-month-old daughter, Aubree, is recovering from a gunshot wound to the head.

Stykes and Aubree were found in their car in Ripley, about 45 miles southeast of Cincinnati. Police initially thought they were responding to a car crash, but authorities now say at least five shots were fired at Stykes' car.
