Hamilton Spectator June 7th 2011 basically the "expert" is saying that the case won't be solved unless the perp commits another crime not something we can hope for.
"When investigators spend months building a case around a particular suspect and then that case falls apart, it can be almost impossible to go back to the beginning, he said, adding that a considerable amount of time and resources have already been spent.
Barring a major break, such as a sudden DNA match or new eyewitness coming forward, these cases go cold and are not solved, Brienza said.
Its become a trend for police to believe forensic tests will back up their cases, he said. Investigators are now under double the pressure to find a violent killer and to reassure the public they are safe.
James Adcock, a professor, author and cold case expert who consults police in the United States, said police services investigating homicides often fall victim to booby traps, including tunnel vision.
DNA only solves about 30 per cent of cases, he added.
In his opinion, and without having read the police notes on the case, he said Scott doesnt meet the profile of the murder.
People who behave oddly can be easy targets, he said.
Given the severity of Gleaves beating and her extremely private and quiet lifestyle, Adcock believes the murder was done out of anger and was likely committed by someone she knew, someone who was watching her or someone with issues related to women.
Police need to go back and start again with the victims profile, he suggested. If you know your victim, you know your murderer.
In most homicide investigations, the killer is known to police within the first 30 days but may not be considered a suspect because they are nice or co-operative, he said.
Adcock warned that unless Gleave was murdered for a deeply personal reason, there is a likelihood the killer could strike again.
This is not going to be the last, he said.
Adcock also suggested police look for sexual assault cases in the area. There is a still-unexplained sexual component to Gleaves murder."
