The family of a former York mayor and attorney is offering a $10,000 reward in his murder case.
The victim's girlfriend was convicted but police say she didn't act alone.
Eyewitness News talked to the victim's sons Friday and they want answers but leads haven't brought any new arrests in the murder of Melvin Roberts yet.
Now, York police, the Sheriff's Office and Roberts' sons hope a $10,000 reward will bring answers.
"Let the community see that you know we're still 100 percent involved in solving my father's case," said David Roberts, victim’s son.
The prominent lawyer and former mayor was murdered after returning home from work in February of 2010.
Roberts' long-time girlfriend Julia Phillips was convicted of the murder.
Police said it has been an exhaustive investigation with a lot of information to process.
"Melvin Roberts, as a defense attorney and as a businessman, had a lot of dealings with a lot of people and it's just a matter of being able to go through the amount of information that we have," said Lt. Rich Caddel with the York Police Department.
Investigators said they've received leads as recent as last week and that gives David Roberts hope.
The case is also getting national attention.
The family said later this month, it will be profiled on Investigation Discovery's crime show "Southern-Fried Homicide.”
"It's seems like right now there is a lot of momentum in my dad's case and I'm really hopeful that this show -- the reward -- will bring that person forward," David Roberts said.
