Seth said he had to go. Two minutes later, he was shot.

“What happened in those two minutes?” Joel Rich asked. “We’d love to know.”

They said it’s clear there was an altercation because Seth had bruises on his hands and his face. Joel Rich said his son would not have risked his life in such a struggle if a gun was apparent from the start.

“So he was just trying to defend himself, and then he turned and he was shot,” Joel Rich said.

Seth would have been aware of robberies in the area in recent weeks, Rich said, and noted that the signs of struggle included damage to Seth’s watch.

“There were no shell casings — it was a revolver,” Joel Rich said. “So it wasn’t, quote, ‘a professional’ kind of weapon.”

In addition to seeking information from the public, Burkman raised the possibility that more private security video could be discovered, and said there are plans to do a re-enactment of the crime.

Burkman said that re-creating the crime scene is a way both to garner more information and generate additional public interest in the case.
