A former undercover RCMP officer, turned antique shop owner in Prince George, B.C., is back in jail after violating parole for the decades-old murder of his wife.

Patrick Kelley was sentenced to life in prison for pushing his wife Jeanette off the 17th-floor balcony of their waterfront Toronto apartment building in 1983. He was granted full parole in 2010 and moved to Prince George. 

Now Kelly is back in prison after failing to tell his parole officer he was involved with three women, at the same time, between May and August 2012.

'Your recent behaviour on full parole compares with a previous pattern of criminal behaviour '—Parole Board of Canada decision

The Parole Board of Canada said it was concerned Kelly was repeating what it called a "deceitful pattern of behaviour," and hadn't been completely honest about his criminal past with the women he was dating.

Parole Board documents show Kelly eventually admitted to his parole officer that he had not disclosed his intimate relationships, feared he was developing a drinking problem, and had begun lying to customers about what work had been completed.

"Therefore, your recent behaviour on full parole compares with a previous pattern of criminal behaviour given your deceit, relationship dishonesty and the potential for financial stress," ruled the Parole Board decision.

Prior to killing his wife, Jeanette, Kelly had extra-marital affairs with multiple women and during the trial prosecutors accused him of killing her to cash in on an insurance policy in order to relieve debts.

Return to jail shocks friend

The decision shocked close friend Rebecca Sinclair, who knew of Kelly's past problems with the law.

"The last person he called on his cell phone before they took it from him was me, and he said, 'Go to my house. Get my keys and take care of my stuff.' "

Sinclair has agreed to close Kelly's antiques store on his behalf, which he has run in Prince George since 2010.

"I don't know if he'll ever get re-instated in the community or not, but I'm going to assume that he won't, and then if he does, he can start from scratch again."

Kelly's parole could be up for review again next year.

Kelly worked undercover in the Toronto RCMP's drug unit until he was charged with his wife's death. He has always maintained her fall was an accident.
