Another explosion badly injures woman in Austin

Police responded to another explosion in Austin that badly injured a woman, hours after a package bomb killed a teenager and wounded a woman in a different part of the city.

Austin-Travis County EMS tweeted that an explosion Monday in southeast Austin injured a woman in her 70s, who has been hospitalized. A second woman from that address has been hospitalized with an unrelated medical issue.

Authorities have not said whether the most recent explosion was caused by a package bomb like the one that exploded earlier Monday.

Police Chief Brian Manley said at a news conference Monday that investigators believe the deadly blast Monday is linked to a March 2 package bomb that killed a 39-year-old man in another part of the city.

Police say their investigation of deadly package bombings at two Austin homes will try to determine if a hate crime was involved because the victims in both cases were black.

Police Chief Brian Manley said Monday that investigators hope to collect surveillance video from nearby homes to identify a suspect.

He says there's currently no other evidence indicating a hate crime beyond the victims' race.

He says the package that exploded Monday and the one that detonated on March 2 had been left on the front doorsteps and were not delivered by a mail service.
