Saint John’s deputy police chief has been cleared of any potential wrongdoing in connection with the investigation into Richard Oland’s murder.
Saint John Police Chief John Bates asked the Halifax Regional Police in January to conduct the investigation.
While Dennis Oland was on trial last year for the second-degree murder of his father, one witness testified that McCloskey, then an inspector, asked him not to testify that McCloskey had been at the crime scene.
McCloskey himself denied the allegation when he took the stand.
Evidence presented during the trial suggested a number of problems with the investigation, including a failure to properly secure the crime scene, prompting the Saint John Board of Police Commissioners to ask the provincial police commission to conduct an inquiry.
Halifax Regional Police have concluded their eight-month investigation, which included consultation with the Nova Scotia Public Prosecution Service, and cleared McCloskey of any criminal wrongdoing.
They say there was no evidence to support charges being laid against McCloskey.
The Oland family operates Moosehead Breweries -- the oldest independently owned brewery in Canada -- although Richard Oland left Moosehead in 1981.
Oland's body was discovered face down in a pool of blood in his Saint John office on July 7, 2011. He had suffered 45 blunt and sharp force blows to his head, neck and hands.
Dennis Oland was convicted of second-degree murder in December and sentenced to life in prison with no chance of parole for 10 years.
He is seeking release pending the appeal of his murder conviction.
