Organizers of the South By Southwest festival are urging those visiting Austin, "if you see something, say something", after three package bombings killed two people and injured two others in less than two weeks.
He said officials believe this explosion is related to two previous explosions - one that occurred earlier on Monday, another that happened 10 days ago.
Austin-Travis County EMS tweeted that the later blast left a woman in her 70s with potentially life-threatening injuries and that a second woman in her 80s was being treated for an unrelated medical issue.
Manley said Monday's first explosion is similar to the March 2nd explosion and is "likely related".
Although investigators have not determined a motive for the attacks, they believe the victims may have been specifically targeted due to their race.
A 75-year-old woman was severely injured in the afternoon attack.
Manley said the packages are "average sized delivery boxes, not exceptionally large" that the residents found outside their houses.
McManus said in a news conference he has been in contact with Manley, who shared that Austin PD has been receiving a lot of calls from people across the city reporting suspicious packages.
"We are putting together a task force that will work jointly until we conclude this investigation and we arrest the person or persons responsible", Manley added.
Anthony Stephan House, 39, died from injuries in the March 2 explosion, police said. His death is being investigated as a homicide.
The police say the devices are powerful enough to cause extensive damage inside the homes and showed a certain amount of sophistication.
"There was a package that exploded inside of the home".
He said officials with the USA post office and large package delivery services, including UPS and Federal Express, have no record of dropping off parcels to the three addresses. If you receive a package that you are not expecting or looks suspicious, DO NOT open it, call 911 immediately. "We can not rule out that hate crime is at the core of this", Manley said. Here's a screenshot of where the explosion took place, east of 35 in the Harris Ridge area, not far from Dell Parmer South Campus and Parmer North.
The F.B.I. and Bureau of Alcohol, Tobacco and Firearms are assisting with the investigation.
