Terry Dittman was killed in 1997...
Police testify about interviews that began to lead them to a suspect
starting in 2001.
Dittman's body was found behind the former Department of Public Works garage on Robinson Street in Binghamton.
She died from a stab wound to the neck.
50-year old Bobby Jo Hatchcock is on trial for Murder in Broome County Court.
A Binghamton detective testified that police questioned Hatchcock in August 2001.
Hatchcock admitted to police that he had sex with Dittman behind the garage, after the two smoked crack cocaine.
He said he didn't remember if he killed her, but that he could have.
Police interviewed Hatchcock again in March 2002.
The detective says Hatchcock claimed Dittman was alive when the two left the garage separately.
A New York State Police DNA specialist also testified that she found semen inside the victim.
The expert says a DNA test shows the semen is a match for Hatchcock.
A garment of clothing taken from Dittman's chest area showed Dittman's DNA mixed with that of 2 other people.
But, in that test, Hatchcock was excluded as a match.
Testimony in the trial will resume on Monday.
