The explosion severed nerves in Wright 's left arm and propelled more than 200 pieces of shrapnel into his body . Kaczynski 's brother , David — who would play a vital role in Kaczynski 's capture by alerting federal authorities to the prospect of his brother 's being involved in the Unabomber cases — sought out and became friends with Wright after Kaczynski was detained in 1996 . David Kaczynski and Wright have remained friends and occasionally speak together publicly about their relationship .
