Three years after the brutal killing of Redner's Markets store executive Gary Redner, police say their investigation has not gone cold.
In fact, they are hoping DNA testing may yield some answers.
Police say in March 2008, Gary Redner was murdered outside his home in the 400 Block of Reber Bridge Road in Lower Heidelberg Township, and his body later found in the driveway.
Investigators say new techniques and procedures have allowed them to re-analyzing old evidence. In the meantime, detectives and police have accumulated thousands of pages of evidence.
Authorities confirm they still receive tip calls on this case on a regular basis.
"Why people haven't come forward with some of these tips until three years later, I couldn't tell you," said Sgt. Raymond Guth of the Pennsylvania State Police. "Even this morning we were getting calls on this."
Not all the tips, however, have panned out. For example, it was once believed that a white-paneled van that was in Gary's driveway around the time he was killed.
"We've never been able to substantiate that," said Sgt. Guth.
But that hasn't slowed detectives down. In Berks County alone there are roughly a dozen investigators assigned to this case. Additional technicians in specialized F.B.I. labs are still going over evidence. And State Police say they continue to look across state lines for clues.
"In fact we have another trip to some southern states planned in the near future to continue to interview people," said Sgt. Guth.
Guth says those responsible for this crime should not feel safe and this investigation will continue.
"We have a pretty good track record, so even as time goes by, I wouldn't feel safe," said Guth, "and eventually we'll find them."
State Police confirm they are awaiting the results for some evidence submitted for DNA testing at an F.B.I. laboratory in Minnesota.
