Police say Pancho Desperatus-Amator-DeTanza, 37, is back at Coquitlam's Cottonwood Lodge psychiatric hospital, after going missing Tuesday morning.

At the time police issued a warning saying he suffers from a mental disorder and should not be approached.

Desperatus-Amator-DeTanza made headlines in 2004 when, according to newspaper Diario ABC Color, he was living in a hotel in Paraguay.

According to the Spanish-language newspaper, he went to the Canadian consulate, got into an argument with an official and shot him in the shoulder.

The victim, Alvin Fehr, survived and Desperatus-Amator-DeTanza​ was sentenced to jail in Paraguay.

The Paraguayan court recognized he had a mental illness, but it is unclear how he ended up back in B.C. at Cottonwood Lodge, which provides intensive psychosocial rehabilitation.
