The vandal arrested in Phoenix wearing a shirt similar to the one seen worn in security images by Robinson was identified by police as 19-year-old Ryder Corral.
Corral stomped through the memorial destroying flowers, vases, flags and other gifts people put down, until a man wearing a blue polo shirt and white hat grabbed ahold of Corral and slammed him to the ground. Law enforcement eventually caught up with Corral, put him in handcuffs and escorted the teen away.

The relative added that they suspected Robinson's politics were influenced by his partner during their year dating.

"I think Tyler got a whole lot worse in the year they have been dating. They are big [video] gamers, and obviously they have that group that influences them as well as others. But my gut tells me [the roommate] did more of the influencing," the relative said.
The FBI is also probing left-wing groups in Utah for possible ties to Robinson or Kirk's assassination, a source familiar with the investigation told Fox News Digital.
Investigators are looking into whether any groups had connections to Robinson, knew about his alleged plans beforehand or assisted him in carrying them out.
