Scott Stradling was arrested Wednesday night in the killing Saturday of 57-year-old William Henry Harrison at Stradling's home in the Apache Junction area.
Online records indicate Stradling was booked into jail Thursday on suspicion of first-degree murder and criminal trespassing and that he didn't have an attorney when he made an initial court appearance.
A court document said Stradling told investigators that Harrison was shot after Stradling demanded that Harrison leave a motorhome on property owned by Stradling's father.
Harrison had been staying in the motorhome.
