Conditt was killed Wednesday morning after officers said he set off a bomb in his vehicle.
Afterward, police, FBI and the Alcohol, Tobacco, and Firearms agents descended onto his Pflugerville home.

Authorities cleared the scene around 4:00 p.m. Thursday.

The home's windows are boarded, the fence is mangled, and shattered glass sits outside.
Conditt had two roommates.

Authorities are still trying to figure out Conditt's motive.
They said he recorded a 25-minute confession, but it doesn't give a clear answer as to why he created bombs.
