Florida prepares to execute 'Ninja Killer' for 1989 double murder.

Convicted murderer Louis Gaskin, also known as the "ninja killer," was scheduled to be executed via lethal injection in Florida after spending 33 years on death row for fatally shooting a couple in their home in 1989. On the day of execution, the inmate is given a last meal, takes a shower, and is issued clothing before being allowed to make a final statement. The state uses a three-drug protocol for lethal injection, and if something goes wrong, the process will be stopped. After the execution, the warden will sign the death certificate and the body will be removed by a funeral home for an autopsy.
