Federal investigators on Thursday combed through the home of the 23-year-old they say was behind this month's deadly Texas bombing spree, seeking clues about what motivated his attacks the day after he killed himself in a confrontation with police.
Mark Conditt, an unemployed man from the Austin suburb of Pflugerville, confessed to the three-week string of bombings in a 25-minute video found on his cellphone, police said. Conditt blew himself up with one of his own bombs on Wednesday as police closed in on him in his car.
The bombs, which killed two people and wounded five others, primarily targeted Austin, the Texas capital and a fast-growing city of 1 million people. Three were left as parcels outside victims' homes, one by a sidewalk with a trip-wire mechanism attached and two shipped as FedEx parcels, which helped investigators unmask the bomber's identity.
