Thursday marks one year since Danielle Cretacci was shot and killed inside her home in the Town of Tonawanda. Her family and friends gathered Thursday to honor her memory and push for justice.

The last 12 months have been full of sleepless nights for the family and friends of Danielle Cretacci as the investigation into who killed her continues.

"I don't understand how it's been a year and nobody's been charged yet but other murders, people have been," said Joselyn Feeney, Cretacci's niece.

Cretacci, 31, and her two daughters were shot inside their home in the Town of Tonawanda last August. The shooting, which left Cretacci dead, shocked a quiet Tonawanda community and devastated her loved ones.

Feeney said, "She was never out to hurt anybody or harm no one, that's why I don't understand why this even happened to her."

Those who knew Danielle best gathered Thursday afternoon for a candlelight vigil to commemorate their loss. Seeing her face and listening to some of her favorite songs brought back memories and a flood of emotions. 

"I just can't believe this," Feeney said.

This week, Spectrum News learned from court documents there is a prime suspect in the case but no one has been officially charged or arrested.

Feeney urges people to come forward with any information they have that can help law enforcement. 

"We're all heartbroken,” she said. “It's even hurting some of the kids, not all of them but it hurts some that could understand, and it's hard for us to explain to them why it happened because they're still young, and it hurts that us adults have to break the news to them."

But one day, they hope they can tell them good news: that whoever is responsible for Cretacci's death is put behind bars. 

"We need justice. I'll say it until the day she gets it. We need justice," Feeney said.
