BROOKLYN - The defense is expected to call its last witness tomorrow in the Tiana Browne murder trial. Two witnesses took the stand earlier today against the 17-year-old, who is accused of fatally stabbing her cousin two years ago.

The teen's grandmother testified that from the age of 13, Browne was raped multiple times, sometimes by groups of men. She said Browne lost interest in her hobbies - playing tennis, piano and dancing - and ran away from home on almost a weekly basis up until the alleged killing. Browne's aunt supported the claims in her testimony.

A doctor, who may testify that Browne suffers from post-traumatic stress disorder, is expected to take the stand Thursday.
