A reward is being offered for information in the case of a jogger who was murdered in Warwick City Park in May.
Four months after his death, John "Jack" Fay's killer has not been caught.
"The lack of justice is hard," Fay's daughter, Meaghan, told NBC 10. "We don't know who did this. We don't know why they did this. It makes it really difficult in terms of going through the grieving process."
"It's frustrating to have a lack of information. It's frustrating to know we had the worst summer of our lives and this person was still out and free for the summer," Meaghan Fay said.
Warwick police are trying to generate new leads by offering a $25,000 reward for information leading to an arrest and conviction.
The money comes from Fay's family, friends and strangers.
"We want to try anything we can possibly try to get information. It's still unbelievable that this happened," Meaghan Fay said.
Fay, 66, was killed May 17 while taking his daily jog through Warwick City Park. His body was found the next day in a trash barrel covered by debris.
"He's not the kind of person that would start trouble with anybody. He didn't have an enemy in the world. He had a really goofy sense of humor. He was a really intelligent guy, really kept to himself. He was a good dad to me and my brothers ... He just liked to run early in the morning. You shouldn't pay for your life with that," Meaghan Fay said.
Fay's family and the police hope the reward brings the killer to justice.
"We were hoping it wouldn't have to get to this. We were hoping that maybe they would find information sooner. But we're not going to give up and the Warwick police aren't giving up either. We're going to do everything we can until we find this person," Meaghan Fay said.
Police said the killer would likely have wounds to the face, hands and arms as they think there was a violent struggle with Fay. The assailant could have also had poison ivy because of where the attack happened.
Detectives tell NBC 10 they have some promising leads.
Warwick police said anyone with information can call detectives at 401-468-4236 or a tip line at 401-732-8477 or 401-468-4233.
