Xavier is a Mexican man who immigrated from his homeland and stayed in Townville to start his own burritos shop venture. He tried to get a place in Townville's Tourist Convention once but failed, and the convention wasn't ever held again so he missed his only chance to show people what his country was like at the event.
Profiles known from cases
He is foreign (in the USA).
He doesn't wear high heels, isn't right-handed, doesn't speak Arabian and doesn't play the flute.
Xavier got a place in the list of suspects during Hafeez Mrad's murder investigation after the police found out he bore some sort of connection to Jonathan Ross. He said that Hafeez hadn't allowed him to get a stall at the convention, so he went to look for Jonathan's help who tried to do him the favor. This could be a murder motive, though in fact the killer turned out to be the woman from the Irish stall, Elena Bridge.
One day later, he was interrogated because of an argument he'd had with Jonathan as he said he had stolen things from him that were supposed to be part of his Mexican stall. The team was only able to retrieve a bunch of Mexican flowers for him.
