WICHITA, Kan. (AP) — A sheriff’s office in Kansas is seeking the public’s help in the investigation of an Oklahoma man’s death.

Capt. Greg Pollock of the Sedgwick County Sheriff’s Office tells the Wichita Eagle  that sheriff’s investigators are working with law enforcement agencies from both states to find those responsible for the death of 56-year-old Dale Childress of Tulsa, Oklahoma.

Pollock says authorities are asking for information leading to the whereabouts of a dark-colored, four-door Buick LeSabre with a model year between 2001 and 2005.

Childress was named in a search warrant in connection with the shooting deaths of 37-year-old Jennifer Sudar and 26-year-old Amanda Douglas outside a Tulsa apartment complex.

Childress’ body was found last week in the Wichita area with a gunshot wound.
