Puroll, he says, is back on the job, though Babeu doesn't allow range deputies on solo patrols anymore.
"He's out there stubborn as ever, doing his thing," Messing says of the deputy. "That's just Louie."
Messing continues as he drives back toward I-8 and civilization:
"My own opinion is that Louie is clean... but I don't have all the answers. Maybe there are people out there who do."
Drs. Baden, Spitz, and Di Maio independently examined the photos taken of Puroll's gunshot wound before replying to New Times.
"There is black powder along the edges of the [wound], a furrow along the edges," says Baden, who also is the chief forensics consultant to Fox News and, thereby, one of the more visible forensic pathologists in the nation.
"You just don't see that in distance wounds. Also, the pink discoloration around the outside of the wound is from carbon monoxide that always shows up when a weapon is fired at close range."
He adds, "If someone wants to cause a grazing wound, they can easily do that without fear of sustaining a more serious injury than this individual sustained."
Di Maio says, "That looks to be a contact wound. It's got all that suspicious red color, which is carbon monoxide and usually means contact, and [there is] all that black stuff around it, which gets you thinking it probably is soot from the contact wound."
But he says he's not comfortable with rendering a definitive opinion.
"The area around this superficial wound should be seared — the bullet came through at 1,400 degrees, you know — but I don't see any soot or searing. It's real complicated. Soot could have been wiped away from the wound, and we don't know exactly at what point in treatment [of the injury] that the photos were taken. But I think that this case [would] be called on the T-shirt, not on the wound."
Luke Haag, president of Carefree-based Forensic Science Services and author of Shooting Incident Reconstruction, says, "If there are issues about direction and distance, and the first thing that bullet hit was clothing, the clothing will win the day for somebody. That shirt would tell you whether it's contact, near contact, or a distance shot."
Haag adds, "Pinal County's not submitting that T-shirt for testing is definitely troublesome. Sometimes, the police don't wear the white hats. I hope that's not the case here."
Retired homicide cop Weaver Barkman says Louie Puroll's story doesn't work on a number of levels.
"Were the deputy not a law enforcement officer," he says, "the conflicting evidence would likely result in a finding that his claims were fabricated and expose him to criminal and civil action."
Dr. Pitt, the forensic shrink, also remains unconvinced:
"This case has a divide the size of the Grand Canyon between the behavioral evidence and the physical evidence. Until people are going to be able to explain that divide, Deputy Puroll needs to be considered a suspect in this shooting."
