He had heard the explosion and went out onto the street to see what happened. According to court filings, House had a 6-year-old daughter at the time of his bankruptcy. A second woman from that address has been hospitalized with an unrelated medical issue.
"My prayers are with the families of those that lost their life or injured during the three explosions".
"Very scary. Just in total shock".
"We will respond", Manley said.
"The world is just filled with insane people, that in their minds, the only crime is how you were born", says Jay Brewer, neighbor.
The first blast happened just before 7:00 Monday morning when a resident took a package from the front porch inside a home. Officials are warning residents to not open any unknown packages.
FBI teams from Austin, San Antonio and Dallas were investigating as was the Bureau of Alcohol, Tobacco, Firearms and Explosives.
Police believe the package was not handled by the U.S. Postal Service or private mail carriers. Anthony Stephan House, 39, was killed by the blast, but his death was not initially ruled a homicide because it was an "isolated incident".
Monday's second explosion - the cause of which was still being investigated - happened in the Montopolis neighbourhood, near the airport and about five miles south of the day's first blast. "It's kind of one of those things that hits you from the side, especially knowing it's one of your neighbors even though you didn't know them directly", says one neighbor.
"I'm scared for everyone's safety", she told the American-Statesman in Spanish.
Davis says she's friends with the woman who was injured, who she says is the mother of the 17-year-old who died.
Manley said the packages are "average sized delivery boxes, not exceptionally large" that the residents found outside their houses. She was reported to be in critical condition with life-threatening injuries.
"We don't know what the motive behind these may be", he 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.
"We will not tolerate this in Austin", Manley said. If you're at SXSW, you should probably be more cautious for odd packages if you're staying at a home that's an Airbnb, since the three packages so far have been left outside of homes. The explosions were not in the immediate vicinity of the festival and authorities say the bombings don't appear connected to the festival.
"We are imploring the community, if you know anything about these attacks, it is imperative that you come forward", Austin police chief Brian Manley told a news conference.
The package bomb attacks come as almost half a million visitors converge for the South by Southwest music and film festival, a time when national attention is usually focused on Austin for celebrity sightings and other entertainment news.
All residents of Austin are advised to be cautious of the packages they receive. The package detonated upon opening and a 17-year-old boy lost his life.
