A massive manhunt is taking place in Texas.

Texas police and residents are on high alert and Gov. Greg Abbot has offered a $15K reward for arrests after a series of deadly package bomb attacks reminiscent of the “Unabomber” have stunned the city of Austin.

A teenager was killed and at least two women were seriously hurt after a pair of explosions rocked homes in Austin on Monday — just two weeks after a separate blast which authorities said is believed to be linked to both incidents.

The first explosion occurred on March 2, killing 39-year-old Anthony Stephan House after a “device” exploded on the front porch of his Austin home. The blast was initially investigated as a suspicious death, but is now being viewed as a homicide.

Monday’s attack occurred just 12 miles from House’s home. Though investigators believe the package bombs are linked, they said it’s too early to “assign a motive.”
