And the NSW Police Force will

continue to use this science because it enables police to solve crimes months after they have been committed, the NSW Police Minister David Campbell announced last week.

And it was a week in which two of the hundreds of previously unsolved cases referred to by Mr Campbell were being finalised through sentencing of gaol inmates at the Bathurst Court House.

The two cases before the Local Court related to breaking, entering and stealing of valuables from home units, one at Granville in February 2006 and the other at Summer Hill in June, 2007.

In each instance the perpetrators of the crimes had left behind spots of blood from injuries they received.

One by bleeding after breaking a bathroom window and the other bleeding from a cut caused by smashing a glass sliding door to get into premises.

One of the defendants Jason Anthony McGoldrick, 38, was brought from the Bathurst Correctional Centre (where he is serving a sentence until August 2008) to plead guilty to smashing a rear sliding door to enter premises in Meehan Street, Granville between 7am and 4.30pm on February 3, 2006.

McGoldrick had stolen rings, earrings, bracelets and watches valued at about $8,000, and $2,000 in Australian currency from envelopes in a drawer after he rummaged through a master bedroom and spare room in the dwelling.

Crime scene investigators had found spots of blood on a western wall in the master bedroom and on two grey pillows from which swabs had been taken.

There were also fingerprints on a green box that had been touched in the spare room by McGoldrick.

McGoldrick’s DNA had been positively matched by police who came to Bathurst on November 14 last year to interview the prisoner who had been taken to Bathurst Police Station.

But McGoldrick had declined to be interviewed.

He was convicted last week on the charge of breaking, entering and stealing and sentenced to a concurrent seven months gaol dating from January 14, 2008 expiring on August 13, 2008.
