A gun that became part of cop-hater James Roszko’s small arsenal in an ambush was wiped clean and put into a bag by two men accused of assisting him in the murder of four Mounties.
That was one piece of evidence from a court-agreed statement of facts that led to Shawn Hennessey, 29, and Dennis Cheeseman, 25, quietly admitting their part in the brutal 2005 murders, in a jam-packed courtroom yesterday morning.
The pair pleaded guilty to four counts of manslaughter in the deaths of the officers, who were raiding Roszko’s Mayerthorpe-area marijuana grow-op on March 3, 2005, before the gunman opened fire.
The brothers-in-law were initially charged with first-degree murder after their arrests in July 2007, but agreed to plead to lesser charges. New details in the investigation were revealed yesterday. DNA evidence found in a glove on Roszko’s farm after the massacre, and registry records confirmed one of the firearms used belonged to Hennessey, and the pair admitted giving Roszko a ride to his farm after the incident.
After killing the officers, Roszko turned the gun on himself.
