YORK, S.C. -- A former mayor of York was laid to rest Monday while the search continues for his killer.
Investigators say they have no suspects and no motive in the murder of Melvin Roberts.
Police say the killer attacked Roberts' girlfriend, leaving her bound and gagged outside Roberts' home. She told police the man waited for Roberts to get home and then killed him in the driveway.
Roberts was 79 years old.
His funeral was held Monday afternoon at the First Presbyterian Church in York.
"Melvin Roberts gave me my first job in the law field," said attorney David Guyton, who attended the funeral.
York police and officers with the State Law Enforcement Division said they are pouring over evidence and leads. A 911 call and artist rendition sketch of the killer have not been released to the media.
Police haven't ruled out the possibility of a disgruntled client looking for payback against Roberts.
"It happens all the time," Guyton said.
Police say Roberts was attacked as he got out of his car. Police say he had a plastic tie around his neck, plus ear and head trauma.
The call initially came in as a robbery, but police said it doesn't look like the killer took anything.
Guyton says the idea it could have been personal has fellow attorneys considering gun permits to protect themselves.
"I'm not planning on it right now, personally, but it has crossed my mind because of this," Guyton said.
