Former Oakland Raiders defensive end Anthony Smith was sentenced to life in prison without parole on Friday (Jan. 22) for three murders dating back to 1999.

A Los Angeles County jury convicted the 48-year-old of three counts of murder… with special circumstances of torture, kidnapping and multiple murders back in November. This past week, he was sentenced to three consecutive life terms without the possibility of parole.

The former NFL player is said to have posed as a police officer to kidnap brothers Ricky and Kevin Nettles from their Los Angeles car wash business on Nov. 10, 1999, before killing them.

Then on June 24, 2001, Smith kidnapped Dennis Henderson, before beating and stabbing him to death.

He was also accused of the murder of friend Maurilio Ponce, whom he lured to an Antelope Valley desert highway in 2008, where he was beaten and shot after a business deal went bad. A jury was unable to reach a verdict on the fourth charge.

The murders remained unsolved, up until 2011, when Smith was arrested without bail.

Smith was the No. 11 overall pick of the 1990 NFL Draft by the Raiders. During his NFL career, he recorded 57.5 sacks and 190 tackles, before retiring in 1998.
