A 46-year-old man wanted on a nationwide warrant in connection with a violent October attack in northern Arizona was arrested at a Legoland theme park in Southern California, the Yavapai County Sheriff's Office announced. The man, identified by authorities as Jason Marchesano, was the focus of a months-long, multi-state manhunt after what the sheriff's office described as a violent attack on his girlfriend in Paulden on Oct. 28, 2025. Marchesano is accused of homicide, assault and kidnapping in connection with the incident, and the warrant that led to his detention was issued on those allegations.
The arrest, announced by the Yavapai County Sheriff's Office, brought to an end an extended search that crossed state lines. Authorities said Marchesano was detained at Legoland in southern California; beyond the location of the arrest and the fact that he had been sought on a nationwide warrant, the sheriff's office described the original incident in Paulden as a violent attack on his girlfriend. Paulden, where the reported attack took place, is an unincorporated community in Yavapai County located north of Prescott and west of Sedona.

The Yavapai County Sheriff's Office issued the announcement of the arrest after Marchesano's detention at the Southern California amusement destination.
