Police Warn Of 'Suspicious' Packages As More Explosions Rock Texas

The scene of a deadly package bomb explosion in East Austin

A 17-year old boy has been killed and a woman in her 40s injured in a bomb blast in Austin, Texas on Monday, 10 days after a man died in a similar attack.

Austin-Travis County EMS tweeted that an explosion Monday in southeast Austin injured a woman in her 70s, who has been hospitalized. Anthony Stephan House died after the explosion on his front porch around 6:55 a.m. March 2, on the 1100 block of Haverford Drive, which is about 12 miles away from Oldfort Hill Drive neighborhood.

Austin police Chief Brian Manley said at a news conference Monday that the U.S. Postal Service does not have a record of delivering a package to the Austin home where the explosion occurred Monday.

"The evidence makes us believe these incidents are related", he said, saying investigators have not come up with a motive or whether anybody has claimed responsibility. Along with a first explosion on March 2nd, which killed a man just north of Austin, CNN reports the authorities are now trying to determine whether or not all three incidents are connected. "We do know that both of the homes that were the recipients of these packages belong to African-Americans, so we can not rule out that hate crime is at the core of this".

Austin Police Chief Brian Manley said the APD and the USPS will work with the Federal Bureau of Investigation and ATF National Response Team along with other agencies to investigate and they will "leave no stone unturned".

An Austin TV station reported that the Monday explosion happened shortly before 7 a.m.at a location about 11 miles from the March 2 explosion.

He also confirmed that additional K9 explosives units have been brought in to the city to assist with the investigation. He at first suggested that the blasts could constitute a hate crime, but later amended that to say authorities had not settled on a motive.

Correction: A previous headline for this story on the CNN app incorrectly stated that the explosive packages were connected to the South By Southwest Interactive Festival, now taking place in Austin.

Due to a high level of calls, Manley noted that it may take officers a little while to arrive, but he said "we will respond".

The victim of the second Monday blast was a woman in a wheelchair who had been watering her grass, said Brandon Rendon, a 27-year-old contractor who lives four houses down from her home in the mainly working-class Hispanic Montopolis area.

Police didn't immediately identify the teenager killed Monday.

The female's injuries were not life-threatening, he said.

Police initially investigated a second package they found in the home, but determined it was not a danger.

"If you've received a package that has been left on your doorstep or left in your yard or left on your driveway that you were not expecting ... then give us a call."

The three explosions occurred in different parts of east Austin.
