EAST NEW YORK - Police have made no arrests since 18-year-old Tanaya Copeland was stabbed to death in East New York a year ago Saturday.

Rochelle Copeland, the victim's mother, says the wounds are still fresh.

"You have your kids, no matter how angry you are at them, let them know you love them before you leave," Rochelle Copeland says. "You never know, you may come home and you may never see them again."

Police say a cab driver discovered Copeland's body on Stanley Avenue. Police arrived and found she'd suffered more than 30 stab wounds.

Part of the brutal attack was caught on fuzzy surveillance video, police say. That video has never been released to the public.

A knife was recovered at the scene, but police say they couldn't get a strong enough DNA match to pin the attack on any specific person.

Three days after Copeland's murder, two children were stabbed in a NYCHA building elevator just blocks away. PJ Avitto, 6, was killed, and Mikayla Capers, 7, was badly injured.

Daniel St. Hubert was arrested and charged in that case. Police had originally called him a person of interest in Copeland's slaying, but no charges have been filed against him in that case.
