AUSTIN, Texas – A teenager is dead and two people are in the hospital after two separate packages exploded on Monday in East Austin.

The explosions come ten days after a man was killed following a similar package explosion on March 2 on 1112 Haverford Drive.

The first explosion on Monday happened 6:50 a.m. at 4800 block of Oldfort Hill Drive near East Martin Luther King Jr. Boulevard, between 183 and Springdale Road. This explosion killed 17-year-old Draylen Mason and injured an adult woman.

The woman's injuries are not considered life-threatening.

The second explosion on Monday happened at 6700 block of Galindo Street around noon. A 75-year-old Hispanic woman was seriously injured after she picked up the package and it exploded. She was taken to Dell Seton Medical where she is in stable but critical condition. Manley said that her injuries are being considered life-threatening.

In all three cases, packages have been found on the front porches of homes and detonate when the residents pick up the packages.

None of the packages are said to be delivered by USPS, UPS, FedEx or any other postal service.

In an afternoon press conference, interim Austin Police Chief Brian Manley said that all three explosions are likely connected, but could not say if the victims were chosen at random or if they were targeted.
