AUSTIN, Texas (KKTV) - Barely an hour after the Austin Police Department announced two separate deadly package explosions were linked, a third explosion was reported at an Austin home.
This time, the victim survived the blast but still suffered life-threatening injuries. She has only been identified as an elderly woman in her 70s.
The latest explosion to rock the Texas capital came five hours after an explosion in a quiet east Austin neighborhood killed a teen boy and injured a woman in her 40s. Police said it shares similarities with that detonation and a fatal blast at a home in north Austin March 2.
In the all of the blasts, the explosive was encased in a package that was left on the front porch. None was delivered by mail services.
The victims in the first two blasts were black; the third, Hispanic. Police say racial motivation is being considered as a possible motive, but all other possibilities are being considered as well.
According to Austin police, Monday began with an "urgent" 911 call just before 6:45 a.m. local time at a home in Austin's Windsor Park neighborhood.
"Upon arrival ... what we found was an explosion had occurred inside the residence. There were two people that had been injured," a police department spokesperson said.
The surviving woman's injuries are potentially life-threatening, according to CBS Austin. The teen, identified only as a male around 17, died at the scene.
Neighbors were evacuated to a city bus that had been on its morning route in the area. Bomb-sniffing dogs went from home to home checking for any other explosives. None were uncovered.
