A man was arrested on suspicion of first-degree murder and prohibited possessor charges in connection with a 2013 shooting on Tucson's south side. 

Micah J. Waggoner, 33, was already booked in the Pima County jail on unrelated charges when he was arrested March 8 for his role in the shooting death of 42-year-old Marlon Patterson who was found lying in the driveway of a home in the 1000 block of East 24th Street on Oct. 29 2013. 

Waggoner was brought in to the jail on March 6 on suspicion of aggravated assault with a deadly weapon/dangerous instrument, dangerous drug possession/use, misconduct involving weapons and failure to appear, according to jail records. 

Waggoner was acquitted of first-degree murder in 2003 for the Jan. 12, 2002, shooting deaths of Ralph Courtney Mitchell, 19, and his 18-year-old girlfriend, Samantha Smelker, according to Star archives. 

The couple was found dead at a home in the 2300 block of East Parkside Drive, near East 36th Street and Kino Parkway.

Waggoner, who was 21 at the time of the shooting, and his brother were both initially charged in the couple's murder. Charges against the brother were dropped. 

Pima County Superior Court Judge Charles Sabalos, who has since retired, ruled that prosecutors proved it was more probable than not that Waggoner committed the murders, but did not meet the higher legal standard of proving guilt "beyond a reasonable doubt," according to Star archives.
