Police beginning to rule out "bike path rapist'

Whoever killed
Joan Diver didn't leave any DNA evidence, according to forensic tests conducted over the last five days.
And that finding is steering investigators away from the theory that the "bike path rapist" killed the Clarence mother of four.
"We have not gotten any confirmation of any foreign DNA," Erie County District Attorney Frank J. Clark told The Buffalo News on Friday, adding that more tests are being done.
Clark's announcement came as family and friends gathered Friday morning at the Zion Lutheran Church in Clarence Center for
Diver's funeral.
The day also marked a full week since she dropped off her youngest son at day care before heading to the Clarence bike path - and vanishing. A volunteer searcher found her body Sunday in thick brush off the bike path near the Clarence-Newstead border.
Late Thursday, sheriff's investigators secured a warrant to search
Diver's Ford Explorer, which was found parked on Shisler Road in Clarence, where the road intersects with the bike path.
The vehicle could provide clues to
Diver's death: authorities received a tip that it was seen at another spot along the bike path last Friday morning.
Sheriff's officials said Thursday the lawyer for Diver's husband, Steven T. Diver, a chemistry professor at the University at Buffalo, had been stalling on giving permission to search the vehicle. But the search warrant negated that issue.
The husband is not considered a suspect or a person of interest in the case, sheriff's officials have said.
Authorities initially suspected that
Diver may have been the victim of the elusive "bike path rapist" linked to nine sexual attacks on women in Amherst, Buffalo and Hamburg in the 1980s and 1990s. Two of his victims were killed during the assaults.
An autopsy revealed no signs of sexual assault but other similarities between
Diver's death and the bike path rapist cases were indeed striking:
First, she was a woman attacked on a bike path. The bike path rapist approached his victims on bike paths, a park and near railroad tracks.
Diver went missing 16 years to the day that University at Buffalo student Linda Yalem, the victim of the bike path rapist, was killed on an Amherst bike path. On Sept. 24, a memorial run was held for Yalem on the North Campus. The autopsy showed Diver had been strangled with some sort of ligature. She also suffered some form of "blunt force trauma." The ligature was the bike path rapist's trademark. He used a device that didn't leave any fiber or other trace evidence behind when wrapped around his victims' necks. He usually used the ligature to render this victims unconscious, before raping them.
Diver's body was found partially clothed. The bike path rapist always raped or tried to rape his victims.
Investigators in the
Diver case were waiting for results of forensic tests from her body that could have been compared with the bike path rapist samples.
Police have matching DNA evidence in seven of the confirmed "bike path rapist" cases - including both homicides. Over the years, Erie County's crime lab workers have compared the bike path rapist's DNA profile against tens of thousands of others in law enforcement databases across the country. They have yet to get a hit.
They began to doubt that the bike path rapist had attacked
Diver after the initial autopsy results on her failed to find any signs of a sexual assault.
Now, with no trace of foreign DNA on Diver's body, investigators have no leads. "When you have a woman killed on a deserted country path, normally there's a rape or robbery involved," Clark said. "Neither appears to be a viable motive. So you have to start looking at other areas."
Investigators knew the chances were slim that a serial killer had murdered
Diver.
Studies have shown that most homicide victims usually aren't killed by strangers.
Last year, only a quarter of the nation's murder victims didn't know their assailants, according to FBI figures. An analysis by Washington-based Violence Policy Center of girls and women murdered by males in 2004 showed that 92 percent were killed by a boy or man they knew. In New York State, 88 percent of female victims knew their male killers, the study found.
Investigators in
Diver's murder are now hoping for tips from the public to help them solve the case.
They are also canvassing the neighborhoods and talking to family and acquaintances in search of any possible hints as to who may have killed her - and why.
Anyone with information pertaining to the case or who may have seen Joan Diver, or her car, on the morning of Friday, Sept. 29, is asked to call the Sheriff's Office at 667-5201.
Clarence business owners are offering more than $100,000 as a reward to anyone with information that leads to the arrest and conviction of
Diver's killer.
