Michael Giacona was seen at the corner of Huffmeister and Spring Cypress in northwest Harris County on Saturday.
He was holding a sign that read "I killed Aaron Coy Pennywell while driving drunk."
Giacona was accused of driving drunk when he crashed into a vehicle, killing Pennywell, in June.
Pennywell's friend tells us Giacona served 90 days in jail and will have to spend four weekends holding the sign.
