DNA tech leads to charge against second man in Porter Zip robbery

A Chesterton man has been charged in connection with the armed robbery last year of the Zip Foods in Porter, after DNA technology newly acquired by the Indiana State Police lab connected him with incident, Porter Police is reporting.

A warrant charging Robert A. E. Lewis, 23--no address available--was served on him on Wednesday at the Porter County Jail, where he’s being held on an unrelated charge, police said.

At 9:41 p.m. June 5, 2017, the Zip Foods was robbed at gunpoint. After releasing video surveillance footage of the robbery, investigators received tips enabling them to identify one of the suspects, David Graham, who was subsequently charged, police said.

Investigators also, however, developed information on a pair of latex gloves used in the robbery by a second suspect, Lewis, worn inside the store and then allegedly discarded out of the car window while the suspects were fleeing the scene, police said. Those gloves were later recovered.

When interviewed, Lewis denied any involvement with the robbery. Meanwhile, though the gloves were submitted to the ISP lab, the results showed a mixture of DNA which at that time could not be separated or isolated, police said.

But late last year the ISP lab acquired new equipment “capable of separating DNA in such cases,” prompting Porter PD to re-submit the gloves for analysis, and “the findings support that both David Graham and Robert A. E. Lewis’ DNA were present on the recovered gloves,” police said.

“Investigators would like to thank all of the individuals who provided assistance in identifying the involved persons and information that led to the discovery of the evidence,” police said. “It is the community’s voice that is evident in such cases, as they are willing to get involved and stand against such crimes. This sense of community responsibility is what makes Duneland the community that we all want to live in.”
