Brett Collins (Earth-2)

Brett Collins was a resident of Earth Two and was also the drunk driver that killed Laurel Lance's father.

Drunk driving
At some point in his life, Collins went driving whilst intoxicated and hit the car of an unnamed man head on, killing him. This enraged the man's daughter, Laurel Lance, who later obtained meta-human powers from the S.T.A.R. Labs particle accelerator explosion. After discovering her newfound abilities, Laurel confronted Collins and screamed at him, launching him back and over his own car.

Death
Around 2014, Collins died of unknown causes whilst on his porch.
