The man police had identified as their top suspect in a string of deadly bombings in the Austin, Texas, area made a cellphone recording describing seven bombs he said he had constructed. Investigators discovered the message after the suspect killed himself early Wednesday by triggering an explosion in his car as officers approached the vehicle to make an arrest, police said Wednesday.
Officials identified him as 23-year-old Mark Anthony Conditt, from Pflugerville, Texas, outside Austin.
