Police in New Brunswick have used DNA evidence to crack open an old case, charging a 29-year-old Charlottetown, P.E.I., man nearly a decade after two masked intruders burst into a home and tied up a woman.

The home invasion happened on May 28, 2004, in Petitcodiac, N.B. RCMP say two perpetrators got into the home and demanded money.

A woman was tied up and assaulted. Her son was also attacked when he arrived at the home, police said.

The key to cracking the case, according to the RCMP, was when a suspect was identified through a DNA match in the National DNA Data Bank.

The data bank was created in 1998 and holds DNA samples from offenders convicted of certain crimes. Police can then see if DNA taken from a crime scene matches that of anybody in the data bank.

Michael Arthur Gaudet appeared in Moncton provincial court on Monday. He is charged with forcible confinement, assault, robbery, wearing a disguise with the intent to commit an offence, uttering threats, and break and enter into a home.

He remains in custody and is due back in court on Dec. 5.

Police are still looking for two other men who were involved.
