Austin cops continue search for package bomb suspect

The hunt for the package bomber wreaking havoc in Austin over the last two weeks is ongoing.

Two people have been killed and another two have been injured by the three boxed explosives left at homes in the Texas city since March 2.

“We believe that either the same suspect or suspects are responsible for all three of these attacks,” Austin Police Chief Brian Manley said Tuesday on ABC News’ “Good Morning America.”

But investigators aren’t closer to knowing who’s behind the mysterious attacks.

They’re “to try and determine if there’s any ideology behind these attacks,” the chief continued, because the victims were black or Hispanic.

The situation in Austin worsened early Monday when a 17-year-old boy was killed opening a package left on his doorstep.

An adult woman inside the kitchen with him at the time was hospitalized with non-life-threatening injuries, officials said.

A 75-year-old Hispanic woman was severely wounded five hours later when a package exploded at her Austin home, cops said.

Anna Marie Castillo, whose house if five away from the woman’s, told CNN her parents ran over to see her clutching her face and covered in glass.

"It's really scary and hits really close to home," Castillo said, adding her parents covered the woman in blankets because the blast ripped off some of her clothes.

"I'm worried to look in the mailbox."

The pair of blasts came just 10 days after Anthony Stephan House, 39, was killed by a similar bomb.

There are “specific things we have seen that make us believe all three of these packages were constructed by the same bombmaker,” Manley said Tuesday morning.

Officials investigating the possibility these are hate crimes, but won’t fully commit to that theory.

“It's too early for us to know and I understand the chief is not ruling out any possibility to make sure that they don't overlook anything,” Austin Mayor Steve Adler said on “GMA.”

Police don’t believe the packages are coming through the U.S. Postal Service, FedEx or UPS.

Likely, cops said, the attacker is dropping them off overnight.

Adler asked citizens to be careful when receiving mail that may not look right.

“Well, at this point what we want people to do is be very vigilant,” the mayor said. “We don't want anybody to open or pick up a package that in any way feels suspicious.”
