PFLUGERVILLE, Texas -- Investigators have given the all clear at the site of the serial bomber's home in Pflugerville, but the federal investigation isn't over. There are still questions about Mark Conditt's motives, how victims were selected and how he learned to make bombs.

Gloria Kuempel has lived on the same block, in the Old Town neighborhood of Pflugerville, longer than anyone else. For the very first time in almost 60 years, police her told to evacuate this week.

“You usually think of evacuation if a storm is coming or a flood has come through your town, but it was very different to leave my home,” Kuempel said.

Austin's suspected serial bomber, Mark Conditt, lived just around the corner from Kuempel. Neighbors are trying to make sense of the past three weeks, a series of events that ended so close to home.

“Obviously, you don’t wake up and think you’re living next to a serial killer, but it’s just the times we live in,” Jay Schulze, a neighbor said.

Federal investigators scoured every inch of this yellow home hoping to find answers that the 25-minute recording of Conditt’s confession could not provide. Inside the house, police found homemade explosives. ATF agents left the scene with evidence and two damaged vehicles parked out front were towed away.

Later Wednesday afternoon, the Austin Police Department released two of Conditt’s roommates after questioning. Neither is under arrest.

“It's really is hard for me believe that his roommates, had no suspicions whatsoever," Schulze said.

With federal agents gone, residents want to get back to a daily routine. Pflugerville Adrienne Rubel was walking her dog Barney on her usual route. She said she did not sleep well last night.

“Someone else may get hurt, I don’t want to see that happen," Rubel said. "The sooner this is over, we can get back to normal.”
