An ex-convict has been sentenced to 64 years to life in prison for killing a man with a crossbow in California.

A jury convicted 39-year-old Curtis Scott of killing 62-year-old Angel Martinez in March 2008. Martinez's body was found in Lancaster with an arrow sticking out of his chest. Scott was sentenced Thursday.

Prosecutors say the crime was a random attack that Scott intended to show his stepdaughter he was someone not to be messed with.

Martinez was a retired Edwards Air Force Base employee who was out for a late-night walk when he was struck in the middle of an intersection.
