The district attorney said the shell casing will be tested to see whether it has any DNA on it. He said any DNA found on the shell casing would be compared to Ersland’s DNA and to DNA from two men accused of planning the robbery.
The district attorney said Ersland could be charged with a crime, such as falsifying evidence, if his DNA matches DNA found on the shell casing.
"The technical investigators of the Oklahoma City Police Department swept that whole pharmacy looking for any evidence whatsoever,” Prater said. "That raises my suspicion as to the validity of this evidence. … As in any case, if we find that anyone involved in the case has planted evidence, there are obviously potential legal ramifications for that.”
Ersland denied planting the shell casing, saying he is never alone in the pharmacy. "That’s so ridiculous,” he said. "That would be stupid to do that.”
The security guard, Perkins, 67, stopped protecting the pharmacy in November. Perkins told The Oklahoman
last week, "It is possible he could have put it under there. ... He kept saying, ‘It’s strange that nobody found any of the shell casings from the other gun.’ He repeated that over and over and over.”
Perkins told police Ersland "jumped for joy” when he found the casing, according to the police reports. The guard also reported Ersland said of the shell casing, "That’s the missing link.”
Perkins told detectives Ersland did not want to report the discovery to police because he said he didn’t trust them. Detectives eventually learned about shell casing from the pharmacy’s owner.
The pharmacist’s lead defense attorney, Irven Box, said the value of the shell casing as possible evidence at trial won’t be known until further testing is done.
"It’s just another piece in this gigantic puzzle that we’re trying to work through in regards to Mr. Ersland’s case,” Box said.
