Ottawa Police are prepared to post a reward for as much as $50,000 for information concerning the three-year-old unsolved homicide of Pamela Kosmack.

The half naked, beaten body of Kosmack was found near a bike path close to Britannia Park in June 2008.

Following an autopsy, police confirmed the 39-year-old's death was a homicide.

Her sister, Cindy Kosmack Murch, had posted a reward of $5,000 of her own money over a year ago for information leading to an arrest but so far has had no new information.

Police chief Vern White confirmed Friday, after speaking with Murch, police had agreed to chip in as much as $50,000 but also said the reward could be split among other cases.

The reward would come from the police service operational budget, which means whomever stepped forward with information has to be willing to testify in court.  It will not be offered to "anonymous" sources like in Crime Stoppers, said White, though he said Crime Stoppers posters may be used as part of the campaign.

Det. Francine Typhair of the Ottawa police major crime unit and the case's lead investigator said the reward would be honoured for a year after it is posted.

Only 2nd reward in Ottawa homicide investigation

Only once before in recent history have Ottawa police offered a reward in a homicide investigation.

Police posted a $100,000 reward after the 2007 triple homicide of Judge Alban Garon, a retired chief justice of the federal tax court, his wife and his neighbour.

That reward expired unclaimed.

Murch said she still regularly sees Kosmack's two children, who were 17 and 13 when she died.

But the loss of her sister is felt throughout the family. Since Kosmack's death, Murch said her marriage broke down and she has struggled with anger and depression, and at one time contemplated suicide.

She said she understands solving the case will not bring her sister back but it is something she needs.

"I know there's unsolved murders...my sister's [case] is only three years, and I know there's people waiting seven years, 20 years...I can't deal with that, I'm not strong enough to go day-to-day not knowing who did this to your family member," she said.

"I'm just praying to God that it will help."

Kosmack struggled with addictions

Kosmack had struggled with drug addictions, her family said. After being diagnosed with shingles she was prescribed oxycontin to manage the pain, which she later would exchange on the street for crack.

Murch last saw Kosmack a week before her death when they were playing laser tag with Kosmack's children. At the time, Murch urged Kosmack to get help for her drug addictions.

Kosmack's brother Jeffrey said he battled alcoholism after his sister's death and has wondered if he could have done more. He said the last time he saw her, she asked him for money, which he gave.

"As I was walking away I ended up stopping and saw her walking her away," he said. "That was the last time I seen her. And that's what hurts me...if I would have known something would have happened I wouldn't have let her go."
