Boston Strangler Case Solved 50 Years Later Thanks To A Water Bottle: Albert DeSalvo's Body Exhumed For DNA Testing, How Did This Contribute To The Outcome?

The Boston Strangler case solved almost 50 years later for the murders that no one was ever charged with and it was thanks to a water bottle.

The water bottle was recovered from a construction site where Tim DeSalvo-whose uncle, Albert DeSalvo, had confessed to being the Boston Strangler, which included 13 single women between the ages of 19 and 85 that were murdered in the Boston area. The case is solved that women would be sexually assaulted in their apartments and strangled with articles of clothing.

This two year span of murders between 1962 and 1964 Boston Strangler case was solved recently and possibly puts an official end thanks to a water bottle.

"This is good evidence. This is strong evidence. This is reliable evidence,'' Suffolk County District Attorney Dan Conley told ABC News of the new DNA result. "But there can be no doubt."

The water bottle was left behind at a construction site by DeSalvo's nephew. Authorities reportedly followed the nephew and snatched the bottle when they noticed he left it behind.

First, police had to make sure the Y-chromosomes in those DNA samples were a familial match to Albert DeSalvo in order to convince a judge to let investigators disturb his grave, according to ABC News.. It was a match to the samples collected in the 1964 Beacon Hill murder, excluding 99.9 percent of the male population from suspicion in Mary Sullivan's killing, thus pointing the murder to the man who confessed to be the Boston Strangler.

The killing of Mary Sullivan was believed to be the last one of the 13 killings and that DeSalvo killed her with her stocking. Her killer left behind seminal fluids that were lifted from a maroon blanket her body was covered with. This was the only DNA remaining because it was preserved with five other samples that the Boston Police Crime Lab's lead forensic scientist Robert Hayes preserved as he waited for technology to advance to the point where nuclear DNA could be positively matched to a suspect.

"I knew science would one day provide us with answers in this case,'' Hayes told ABC News.

The body of Albert DeSalvo is being used to confirm the findings to officially put an end to this case 49 years later.

Elaine Sharpe, a lawyer for the DeSalvo family, said that this evidence isn't enough to determine it was indeed Albert DeSalvo and that his nephew did not know he was being followed

"Just because they had DNA,'' Sharpe told an attorney general, "Doesn't mean Albert DiSalvo killed her."

Massachusetts Attorney General Martha Coakley dismissed, saying: "We may have solved one of the nation's most notorious serial killings."
