On September 12, 1996, López mailed a letter bomb rigged with sulfuric acid to Björk’s residence in London, then returned home, recorded a final video diary explaining his motivations, and ended it filming his suicide by gunshot. Hollywood police found his body and the videos four days after his death; they contacted the Metropolitan Police, who intercepted the package. Björk was unharmed.
Probably just a normal course of action in a case like this. I don’t think police will bother if you die of natural causes in your 90s or if you die in a car crash :D
