Merriam murder case ends in guilty plea

An alleged methamphetamine dealer admitted today that he killed a woman at a Merriam motel in January because he thought she was a police informant.

Jason M. Munjak, 37, pleaded guilty this morning in Johnson County District Court to a charge of felony first-degree murder for killing Toby Marie Rock, 37, a mother of five from Topeka.

Munjak also pleaded guilty to a charge of distributing methamphetamine. His sentencing was scheduled for May 30.

Rock had gone to the Homestead Studio Suites on Frontage Road in Merriam on Jan. 19 to buy methamphetamine from Munjak, Assistant District Attorney Sarah Hill said Friday in outlining evidence that would have been presented at trial.

A witness later told detectives that when Rock showed up, Munjak began acting nervously. When she came into the room, Rock said, “What’s wrong Jason? You’re scaring me,” according to the witness.

Munjak pulled out a gun and shot Rock once in the head.

“She shouldn’t have snitched,” Munjak said, according to the witness.

When taken into police custody about a week later, Munjak admitted to police that he had shot Rock, Hill said.

When asked why, Munjak told detectives he thought she was an informant, Hill said.
