Police said Bryan J. Fernandez Hernandez called in a fake home invasion to police when he killed three of his relatives, but new evidence from prosecutors suggests he knew exactly what he was doing.

Initially, police said a tenant, identified later as Bryan J. Fernandez Hernandez, 27, told officers he shot and killed three people during a home invasion at an apartment on Hammerly Blvd in the Gessner Grove neighborhood a little before 3:15 p.m.
