The man accused of killing a Mesa High School math teacher is back in Arizona.

The Tempe Police Department tweeted out on Thursday that Caleb Bartels, 27, is now in the state and will be facing charges for the January homicide.

He was arrested on Jan. 21 by the Susanville California Highway Patrol in the town of Doyle, California.

Police launched an all-out search for him, but not before he was stopped three times by law enforcement in Arizona, Nevada and Utah.

Then on Jan. 21, an off-duty officer with the California Highway Patrol first spotted the vehicle belonging to Bartels parked alongside a highway near Doyle. He called on-duty officers and Bartels was arrested without incident.

A judge set his bond at $1 million.
