SALT LAKE CITY — Federal prosecutors are recommending a Brigham City doctor who illegally prescribed painkillers spend 20 years in prison.

Dewey C. MacKay, 64, was convicted in August of 40 counts of illegally prescribing pain medication, including two counts that resulted in the death of a 55-year-old man. The jury acquitted him of 44 other counts. The charges related to the death carry a 20-year minimum mandatory prison sentence, while the others carry as many as 15 years in prison.

Prosecutor Michael Kennedy said the 20-year sentence avoids disparity between MacKay and those convicted of similar crimes.

"The minimum mandatory sentence for this offense is applied across-the-board to all defendants convicted of the same crime as the defendant, without respect to whether the drug involved was a 'street' drug such as methamphetamine or cocaine, or a prescription drug such as Oxycodone as in this case," he wrote in memorandum filed in U.S. District Court on Thursday.

Judge Dee Benson is scheduled to sentence MacKay on Dec. 19.
