PLEASANTON — The Pittsburg man accused in the death of two family members has been formally charged.

David Patrick Mcnabb, 31, has been charged with two counts of first degree murder, one count of felony auto theft, and one count of interference with law enforcement, by Assistant Kansas Attorney General Jessica Domme.

The charges stem from a Nov. 12 incident in which the Kansas Bureau of Investigation was requested by the Linn County Sheriff’s office to investigate a crime scene connected to two missing persons from rural Pleasanton, according to a media release.

The missing persons, Betty Mcnabb, 87, and her son, Kenneth Mcnabb, 65, were reported missing by family members late Nov. 11 evening. David Mcnabb is the nephew of Kenneth Mcnabb.

A check of their residence led officers to suspect foul play.

The complaint alleges that on or about Nov. 7, David Mcnabb murdered both Kenneth and Betty Mcnabb and that some time around Nov. 9 stole a 2015 Buick Enclave which had belonged to Kenneth Mcnabb.

The complaint also alleges that David Mcnabb lied to KBI Special Agent Ronnie Burk about the case.

The bodies were discovered near a house in rural Crawford County near Pittsburg on Nov. 15.

The Crawford County Sheriff’s office, the Kansas Department of Wildlife and Parks, the Overland Park Police Department Dive Team, the Missouri Search and Rescue K-9 Unit and the Kansas Highway Patrol all assisted in the search.

The Kansas Attorney General's office has taken over prosecution of the case.
