The family of a young woman found dead in Queens is speaking out for the first time since her death.

30-year-old Karina Vetrano disappeared after going for a run in Howard Beach Tuesday.

She was later found by her retired-firefighter father in the neighborhood's marshland.

Police say she was sexually assaulted and strangled.

Speaking outside their home, Vetrano's parents called their daughter a force to be reckoned with and her killer, a coward.

"My daughter was a big believer of karma and as you can see she’s magical," said Vetrano's mother. "The whole world knows she magical and I guarantee you, you will pay."

"Justice will be served, okay," her father said. "That's why we have the PD. That's why we have God. Justice will be served."

Police believe Vetrano was killed by a stranger.

Investigators found her sneaker and pair of headphones in some weeds near where her body was found.

A $10,000 reward is being offered for any information leading to the arrest of her killer.
