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.
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.
