SAN ANTONIO -

Family and friends of Jerry Collins held a candlelight vigil Tuesday evening at the site of his murder to “keep alive what needs to be taken care of.”

Collins, 68, was found with his throat slit and his head beaten with a hammer on Jan. 28, 2012, in his trailer behind his business, Rittiman Hardware, on the 3700 block of Eisenhauer.

Collins’ sons, Jim and Steven Collins, hope to keep their father’s memory alive while pushing for answers to who is responsible.

"Its a hard thing to deal with knowing that you can’t do anything yourself or move forward or prosecute,” said Jim Collins.

“My brother and I, you know, we get close to hearing something that sounds like good news and it gives us a little extra to keep us going,” said Steven.

What Jerry Collins’ friends and family have heard is complicated.

In late August 2013, Ruth Ann Comer and Kristina Moore were taken into police custody.

Comer was dating Collins at the time of his death and he willed her the majority of his estate.

Investigators believe Comer gave Moore $10,000 to pay someone to kill Collins.

But police arrested Comer in 2013 on suspicion that she was involved in another murder for hire- and this time her target was Moore.

Instead of killing Moore, the person allegedly hired went to police.

Steven and Jim Collins are waiting for that case to move forward and hope it eventually leads to their own closure.

"There's somebody out there who knows something,” said Jim. “There’s someone that someone’s talked to and said something and we just would like for them to come forward.”

The Collins family worked with San Antonio Crime Stoppers to offer the majority of a $40,000 reward for information leading to an arrest in the case. Call 224-STOP to share any tips.

"Just make a call. That’s all we ask,” said Steven Collins. “Just make the call."

The Collins family has filed a wrongful death civil suit against Comer to prevent her from benefiting from their father’s estate.
