An arrest warrant affidavit released Monday details the evidence police have that links Mark Conditt to the Austin area bombings, which left two people dead and several others injured.
The affidavit also revealed that Conditt allegedly used signs to hide explosives.
According to WFAA: Conditt, 24, used a credit card in his name to buy five battery holders matching those used in each of the six homemade package bombs that went off in a span of 18 days last month.
The affidavit also alleges that Conditt may have used signage to conceal some of the explosives. In at least one instance in Travis Country on March 18, investigators believe he hid explosives with a “drive like your kids live here” sign.
Conditt and his red pickup truck were seen at a Home Depot in Round Rock on March 13 paying cash for several signs, including one reading “drive like your kids live here.” Preliminary information indicated the March 18 bomb was detonated with a tripwire.
The report continues: The redacted affidavit, filed 20 days after the last explosion, indicates Conditt is believed to be solely responsible for each of the six bombings. According to the affidavit, “multiple” people have been investigated for ties to the series of attacks, but that none are believed to have been involved.
