ABC affiliate KVUE reported that a male teenager who has not been publicly identified was reported dead on the scene and a woman in her 40s was transported to a nearby hospital with potentially life-threatening injuries.
The FBI and ATF are assisting the Austin Police Department with the case, which is being investigated as a homicide.
Police said that the initial evidence and descriptions of the packages in both cases were similar but did not provide specifics on the appearance of the package.
Police say their investigation of deadly package bombings at two Austin homes will try to determine if a hate crime was involved because the victims in both cases were black.
According to police, one of the two residents found a package early Monday that had been placed overnight on their front doorstep.
