11 a.m. UPDATE: Austin police gave an update on the explosion that killed a teenage boy and injured a woman early Monday morning.

The explosion occurred inside a home and was delivered to the victims. Here is the update from the department's Twitter feed. 

Authorities say a package that exploded inside of an Austin home, killing a teenager and wounding a woman, is linked to a deadly package sent to another home in Texas' capital city earlier this month because they were both left on the front doorstep and not delivered by a mail service.

Austin police Chief Brian Manley said at a news conference Monday that the U.S. Postal Service does not have a record of delivering a package to the Austin home where the explosion occurred Monday.

He says that package was brought into the kitchen where it detonated, killing a 17-year-old boy and injuring the woman. The FBI is helping Austin police in the investigation.
