OMAHA, Neb. (AP) — Police have issued warrants for two prison inmates in connection with a 2012 killing of an Arizona man whose burned body was found in an eastern Nebraska farm field ditch.

Omaha police spokesman Michael Pecha, on Monday, said warrants were issued to 29-year-old John Meyers and 33-year-old Joseph Fleming for use of a weapon to commit a felony and suspicion of first-degree murder in the killing of Jose Quintero.

Sarpy County farmers found Quintero’s burned body in September 2012 after noticing smoke between their fields.

Investigators believe Quintero, of Phoenix, was dead when his body was dumped early on Sept. 24, 2012. They believe he was killed in Omaha.

The men are imprisoned on other charges. They will be booked on the new charges.
