The following describes her use of spells to kill her boyfriend:

Due to a hatred that Jayne developed for her lover, Sam Brody, Mansfield pleaded with LaVey to conduct a ritual of destruction against him. LaVey complied by writing Brody’s name on a piece of parchment and burning it in the fire. As the parchment was consumed LaVey invoked Satan’s powers requesting Brody’s death within one years time. In The Satanic Bible LaVey issues dictums for placing curses on others to bring about their death and concludes by saying: “and if your curse provokes their actual annihilation, rejoice that you have been instrumental ridding the world of a pest!” LaVey’s personal administrator and assistant Blanche Barton comments “No simple undirected curse would do this time. LaVey would only be satisfied when Brody was dead.”

Mansfield states: “Mr. LaVey called me into the back room. There, he told me, ‘The Devil has placed a curse on Sam Brody. There is a heavy black cloud over him…He’ll be killed in a car crash…Get rid of him at once!’”

Scripture says that Satan has been a murderer “from the beginning.” (1 John 3:8 ) Jesus said that Satan’s modus operandi was to “steal, kill and destroy.” (John 10:10 ) Satan is evil to the core and his hatred seethes against mankind, even those who serve him. There is no love or favor in Satan’s kingdom, but a contemptible usage of people who open themselves up to him. Mansfield served Satan, but he hated and despised her. She was only a pawn to further his agenda of worldwide spiritual enslavement under the New Age.

Mansfield’s trust in Satan proved illegitimate as it cost her her life. The Old Testament book of Ecclesiastes says “that those who practice evil will not be delivered by it.” Within a few months, Brody lay dead in a catastrophic car accident. Mansfield was also killed in the crash, and according to her death certificate, suffered a “crushed skull and avulsion (tearing away) of cranium and brain.” Her death was tragic and sudden. Ironically, LaVey reported that 15 minutes before he heard of the accident that he had cut Jayne Mansfield’s head off of a picture with a pair of scissors. Mansfield had truly run her last spiritual red light and the Scripture stating that God will not be mocked came into effect. God’s Word states that your sin will find you out and that those who sow to the flesh will reap destruction.

By placing her trust in Satan, she was deluded into believing that she would have power, success, and protection. Instead, when Satan was done using her to manipulate millions, he threw her away like trash. In spite of her proclamations that Satan was mankind’s “best friend,” he truly was and is friend to none.

If you don’t know Jesus Christ as your Lord and Savior, you can receive Him into your heart, and He can deliver you from darkness and sin and have your name written in His Book of Life.

If you are sincere, you can say this simple prayer to the Father (it doesn’t have to be word for word):

“God, I recognize that I have not lived my life for You up until now. I have been living for myself and that is wrong. Please forgive me of all of my sins just as I forgive others. I need You in my life; I want You in my life. I acknowledge the completed work of Your only begotten Son Jesus Christ in giving His life for me on the cross, I believe in my heart Jesus is Lord and was raised from the dead and I long to receive the forgiveness you have made freely available to me through this sacrifice. Come into my life now, Lord. Take up residence in my heart and be my king, my Lord, and my Savior. From this day forward, I will no longer be controlled by sin, or the desire to please myself, but I will follow You all the days of my life. Those days are in Your hands. I ask this in the Lord and GOD Jesus’ precious and holy name. Amen.”
