Multiple package explosions at separate locations in Austin, Texas, this month have left two people dead and an elderly woman seriously injured. The latest explosions occurred Monday morning.
There have been three package bomb explosions in the state's capital this month, which Austin Police Chief Brian Manley said are likely related.
On Monday, at 6:44 a.m., a 17-year-old boy was killed when he opened a package that another resident had brought into the home and left in the kitchen.
A woman in the home suffered non-life threatening injuries.
The second explosion happened at 11:49 a.m. A woman described to be in her 70s was injured at her home. She was taken to a hospital with serious and possibly life-threatening injuries.
Another woman in her 80s was treated at the scene for an unrelated medical problem.
On March 2, Anthony Stephen House was killed when he opened a package containing an explosive device.
The FBI, Texas Department of Public Safety's K-9 team, and the U.S. postal inspector are assisting the Austin Police Department in its investigation. The national office of the Bureau of Alcohol, Tobacco, Firearms and Explosives is also sending a team to help.
The U.S. Postal Service said the packages did not come through their service, according to police.
Police have issued a warning to residents against accepting and opening packages they weren't expecting.
Texas Gov. Greg Abbott (R) announced a reward of up to $15,000 for information leading to the arrest of the person or persons involved in the explosions.
"As the investigation continues, the state of Texas will provide any resources necessary to ensure the safety of our citizens, and quickly bring those guilty to justice," Abbott said in a statement.
Tips must be submitted through Texas Crime Stoppers.
