The detective did not see the security camera recordings until after questioning Ersland.
Defense attorney Joe Reynolds suggested Ersland mixed up things because he was traumatized. Jacobson disagreed.
“He wanted to tell me about it,” Jacobson said. “It didn't seem like he was that upset about it, in my opinion.”
In the police interview, Ersland said both robbers had guns and both shot at him. He said he was able to get to two guns inside the pharmacy and fired back. He said he shot one robber but the wounded one stayed up and “was gonna hit me as I went by … so I just unloaded … on him and then he fell down and I chased the other guy out.”
Ersland also told the detective a getaway driver with a shotgun was parked in a white Oldsmobile outside the store around the corner. Ersland said he pointed a gun at the driver's head and the man took off.
The detective told jurors the police investigation determined only Ingram had a gun and only the pharmacist fired any shots. The detective also testified Ersland shot Parker five more times after chasing the second robber away, coming back to the store and getting a second gun from a drawer.
The detective said the security camera recordings show the pharmacist had to “walk just about over the top” of the fallen Parker to get the second gun. The detective said the pharmacist also “turned his back to him.”
The detective testified the investigation determined there was no getaway driver with a shotgun parked right outside the store. He said a witness who lives nearby did not see anyone. The witness testified earlier she was in her front yard.
In the police interview, Ersland told Jacobson he had PTSD, post-traumatic stress disorder, from being in the Gulf War. “Yeah, killed a lot of people there,” Ersland said. “But I had to do it. And then I dream about it every night.”
Another homicide detective, Ryan Porter, testified Ersland said he wore a back brace because of an artillery attack while he was in Iraq.
Records show Ersland spent the Gulf War in 1991 as the pharmacy chief at the military hospital at Altus Air Force Base in southwestern Oklahoma.
