The death of Mark Conditt, the man who police say is responsible for the package bombings that caused injury and death across Austin, Texas, was ruled a suicide on Friday, said Dain Johnson, a justice of the peace for Williamson County.

Conditt died from “multiple penetrating shrapnel injuries” from a bomb, Johnson said.

Conditt detonated the bomb inside his vehicle as SWAT officers closed in, Austin police investigators have said.

Earlier this week, police tracked down Conditt at a Round Rock hotel off I-35. Early Wednesday morning, he got into his vehicle, and officers followed him as he drove down the I-35 service road, investigators have said. Officials said he pulled over onto the grass, and as SWAT officers approached, Conditt detonated the bomb.
