FAYETTEVILLE, Ark. (KNWA/KFTA) — Arkansas State Police has turned over investigation files to the Washington County Prosecutor in the suspected homicide of Amber Dunigan.

According to Washington County Prosecutor Matt Durrett, ASP has turned the case over to the county and it is currently under review.

The 36-year-old mother was found dead on May 28, 2021 in a car along Highway 16, parked near the Benton and Washington County state line.

While prosecutors now have the information on hand, Arkansas State Police Public Information Officer Bill Sadler says ASP’s formal investigation doesn’t end until there is adjudication in court or until the prosecutor closes the case. Sadler says it’s not unusual for investigators to continue running leads after a suspect is arrested or even during a trial.

There’s no word on how long it court take for prosecutors to make a decision on naming suspects or charges.
