An Ottawa woman is offering $5,000 of her own money for information about the death of her sister, Pamela Kosmack, who was found slain near a bike path close to Britannia Park in June 2008.

"I'm not waiting anymore," said Cindy Kosmack Murch, 38, Monday. "I'm going to fight to the end … she's a good person and she meant the world to me."

Murch posted the offer of the reward on a memorial Facebook page for her sister on March 24, which would have been Kosmack's 41st birthday.

Kosmack was 39 when her half-naked body was spotted on the edge of the woods by a woman walking her dog on June 4, 2008. Following an autopsy, police confirmed that the death was a homicide. Police told the family she had been beaten, Murch recalled.

No arrests have yet been made.

Murch said police told her they would eventually announce a reward and a profile of the killer, but so far they have not. She was getting frustrated and decided to post a reward herself.

"If I have to, I'll save up more," added Murch, who works as the manager of a condominium building.

Murch said the death has been hard on the whole family including her brother Jeff, 39, her mother, who lives in Ottawa, and her father, who calls every week from Vancouver to ask if there is any new information in the case.

Murch said she was very close to her sister and always went to her for advice. She still visits her sister's daughter, 17, and son, 13, every other weekend.

The sisters shared a room in childhood. Murch described Kosmack as a gifted artist who was quick to help others. She didn't finish high school, but went on to work as a nurse's aide.

Murch choked up as she recalled the girlhood moment when the two sisters learned from each other that they had been molested by the same adult relative.

"She never let me get molested again," Murch said. But she said relatives never believed Kosmack when she disclosed the abuse, and she suggested the experience likely contributed to Kosmack's troubles in her adult life.

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 prescription drug addiction.

She believes her sister knew her killer because Kosmack usually avoided paths and trails away from roadways after dark.
