Billboards are popping up around the Mahoning Valley offering a $20,000 reward to help track a killer.  

The body of Lori Pullin Lynn was found sometime after 7:00AM on August 2, 2017.  She was face down in a pond with a riding tractor submerged in the water at her mother's Shannon Road home in Liberty.

Authorities believe Lynn was actually murdered the day before, on August 1, 2017.

Initially the case was believed to be accidental, but was later ruled a homicide.

According to Diane Pullin of Florida, Lynn's sister they decided it was time to offer a substantial reward because they believe there are people out there who may know information that's valuable to the case.

Pullin says when they decided to put up the billboards, Lamar Advertising provided five billboards free of charge.

The ads that have a photo of the victim say there is a $20,000 reward for any information leading to the arrest and conviction of Lori Pullin Lynn's killer.  

"I feel that they (Liberty Police) do have a good suspect, and we just need harder evidence to be able to get a conviction because I believe that person has hired an expensive criminal defense attorney," Pullin said.

But controversy surrounds the investigation, Pullin tells 21 News she still blames the new police Chief Toby Meloro who initially was a Detective in charge of the case -- for failing to investigate it as proven by Internal Affairs.

"We feel that if he had investigated this murder timely -- because my niece told him who she suspected at that time, and we tried to get them to take the car for evidence, her clothing for evidence, a camera with video for evidence, basically I told them where the car was moved from on the video, and yet they did not investigate.  Their could have been broken prescription glasses, their could have been blood at the scene, those kind of things got missed and washed away.  That hard evidence has been lost because they did not investigate," Pullin said.

The victim's family, including Pullin say it's unsettling that the killer is still out there, "Are we going to be next perhaps -- the ones that are going to strangled or killed?"

But Pullin has hope that someone will come forward to police, tell what they know and do the right thing, she just hopes it's the killer, 
"Well I wish that that person would just confess and get it over with so we can all move on with our lives."

Pullin now has faith in the investigation since a new investigator with Liberty, Captain Ray Buhala has taken over, she says he has worked hard with the help of BCI.

On April 27th at Vernon's Cafe in Niles, victim Lori Pullin Lynn's family will hold a Memorial from 12:00PM to 3:00PM, all family and friends are invited.
