DNA evidence heard at mother-daughter murder trial

DNA evidence took center stage Monday during the trial of an Ossining woman accused of killing her mother.

Ann Trovato is accused of stabbing Patricia Mery 24 times and then beating her to death with a baseball bat in 2006.

Prosecutors tried to link Trovato to the knife they say she used to kill Mery. Three experts from an FBI lab took the stand.

A forensic examiner testified he couldn?t rule out that Trovato?s hair was on the knife. He said the chance the hair belonged to someone else was less than 1 percent.

However, the defense claimed the forensic examiner?s testimony didn?t prove anything. When attorney Alan Focarile questioned the witness, he said it was possible the hair on the knife could have been left by a number of Caucasian people.

Closing arguments could get under way by the end of the week.
