Richland police tracked down 19-year-old Kenneth Callies at a friend's house around 9:00 p.m. on the 1300 block of Williams Boulevard in Richland.
Officers are interviewing Callies and two other people but they are just calling them persons of interest.
His car was later found at the Winco parking lot on Wednesday night.
Earlier Wednesday afternoon, a woman was reportedly held at gun point at her apartment near 4th and Columbia Center Boulevard in Kennewick.
Police say the suspects got away with a laptop, cell phone and keys.
There was a similar robbery just days ago at the same complex.
