Police in Austin have been inundated with suspicious package calls since two package explosions Monday left a teenage boy dead and two women hospitalized. The explosions happened far from the main events of the festival, and there was no immediate word from organizers about additional safety precautions being taken.
The second blast came more than a week later, on Monday morning, and killed a 17-year-old boy.
"The call came in as a nature unknown urgent at 11:50 this morning", the police department tweeted.
The explosions, two of which occurred on Monday, have killed two people and injured two others in Austin and are all believed to be connected. 'Cause the next thing I knew, I saw ambulance with my neighbor on the stretcher.
"The odds seemed very favorable, so I took a walking stick and from behind my door, I cautiously tumbled the box over to bring up the label, where I could verify it was addressed to me and from the expected shipper", Mathis said.
"Are you trying to say something to prominent African-American families?" said Freddie Dixon, stepfather of Anthony Stephan House, the 39-year-old killed in the first explosion on March 2. It's not known if the victims knew each other or if they were targeted, he said. The victim, whose name was not released by police, opened it, and the device exploded, killing him and injuring a woman in her 40s.
Police have said they are not sure if the devices that detonated had all reached their intended targets. ATF is processing any evidence from the first explosion in its lab and will start processing evidence from the second explosion as it arrives at the lab. Neighbors called police after hearing an explosion inside the house.
A woman who gave her name only as Ruby said she lives on the street behind Galindo and was home with her mother at the time of the blast. "Number two, somebody's got some kind of vendetta here", he said, remarking of the third victim, a Hispanic woman who he said he did not know: "Is she a diversion to throw this off, and lead to something else?" Emergency personnel said they transported a female in her 70s to a medical center with potentially life threatening injuries.More news: Chinese parliament clears path for Xi to rule for life
That was about 20 kilometres from the home where the March 2 package bomb killed Mr House.
The March 2 blast was initially investigated as a suspicious death but is now being treated as a homicide, Manley said.
Manley said authorities know what kind of explosive devices were used, but they are not revealing details to preserve the integrity of the investigation. In all three cases, he said, the packages did not appear to have gone through the U.S. Postal Service or private carriers, but were left on doorsteps without knocking or ringing doorbells.
"We will leave no stone unturned because we are not going to allow this to go on in our city", Manley said.
However, a motive in the three incidents remains unclear at this time.
The two victims killed in the explosions are relatives of prominent members of Austin's African American community, the Washington Post reports.
Investigators are looking into whether race was a factor in parcel bombings in Austin, Texas which coincided with the start of the popular South By Southwest (SXSW) festival.
"It looked like small terrorism", he said.
