AUSTIN, Texas (AP) – Federal officials say the suspect in a series of fatal Austin package bombings used PVC pipe casing, a metal pipe and shrapnel in his attacks that killed two people and seriously injured four others.
Authorities on Monday released an affidavit used to support an arrest warrant for suspect Mark Conditt. Investigators used bomb evidence, video surveillance, interviews and phone records to chart a path to Conditt. Police say he blew himself up March 21 as officers closed in to make an arrest.
The document still redacts details about witnesses who were interviewed, phone numbers and places where police say Conditt purchased his materials.
Authorities also dismissed an arrest warrant that had been issued hours before police say Conditt killed himself.
The documents didn’t mention a possible motive for the bombings.
