A suspect who slipped out of handcuffs and escaped a patrol car before being apprehended in a convenience store cooler in McLoud is also a defendant in a Pittsburg County manslaughter case, McLoud police said.

Roy Lee Roberts Jr., 34, remained jailed Wednesday night in the Pottawatomie County Public Safety Center on complaints of escape after lawful arrest, obstructing an officer and carrying a loaded firearm, jail rosters show. Formal charges have not been filed.

McLoud Police Chief Wes Elliott said officers responding to a suspicious vehicle call overnight contacted Roberts in a vehicle and he allegedly refused to exit, prompting a short standoff with that suspect allegedly having a gun. Roberts eventually surrendered to officers, Elliott said, and did have a firearm.

As Roberts was being taken to jail, he was able to slip out of the cuffs and escape the patrol car before running to the convenience store, where he tried to hide in the cooler before being arrested there a second time.

In addition to any new charges that may result from Wednesday's incidents, Elliott said Roberts is also a defendant in a pending manslaughter case in another county.

Court records show Roberts faces that charge for a traffic death in Pittsburg County, where he is scheduled for a jury trial on May 13.
