Box said he believes the charges against Adams could be reduced to second-degree murder or manslaughter.
“They're stretching things,” he said of prosecutors. “They filed charges based on erroneous information.”
Prater could not be reached for comment Tuesday. The lead prosecutor in the case declined to comment.
Justin Adams reported his wife missing in the early hours of Dec. 10, 2011. He told investigators that he and his wife were “swingers,” who both actively used Craigslist to solicit men for sex.
He also said Jaymie Adams was a working prostitute who was meeting clients the night she disappeared.
The defense attorney said prosecutors are trying to link Adams to the murders by allowing his wife to be on Craigslist, that by doing so “he contributed to her death.”
Since Adams was charged, a judge has postponed his preliminary hearing three times to give prosecutors more time to investigate.
In July, Special Judge D. Fred Doak allowed bail for Adams, a rare move for a defendant facing first-degree murder charges.
Doak agreed to set bail at $100,000 and Adams was released from jail a day later.
In October, after postponing Adams' preliminary hearing a second time, the judge signed an order removing Adams' court-ordered ankle monitor.
It was another possible indication that authorities believe someone else committed the crime.
