Police responded to reports of a second explosion in Austin, Texas, on Monday and are trying to determine if the incidents are connected. There have now been three explosions in the city in the last two weeks.
Earlier on Monday, a teenager was killed and a woman was injured when a package exploded inside of a home in Austin. Police believe that incident is linked to a previous incident in which a similar package was sent to another Austin home.
The Austin Police Department confirmed officers were responding to the reported explosion on Monday:
Austin Police Chief Brian Manley is now urging residents not to open suspicious packages and to report suspicious activity to law enforcement as police investigate the explosions:
More from the Austin American-Statesman:
The incidents are being investigated by police and federal authorities, as a homicide, the chief said.
He also said that investigators were not ruling out the possibility of the explosions being a hate crime because the victims in those cases are African-American.
The U.S. Postal Service told investigators that the packages did not come through their facilities, so the packages were likely left by someone at the doorstep, Manley said.
The FBI is reportedly helping the Austin Police Department in its investigation. No suspects or motive have been identified yet.
