Officials from a New York State prison say they want the profits Focus on the Family is making from Son of Sam killer David Berkowitz.
Focus on the Family is offering recordings of an interview with Berkowitz who professes his conversion to Christianity.
The organization is offering the tapes for free but is asking for donations of $7 to $9 dollars.
New York law prohibits inmates from running a business from prison and requires any money they be given to victims and victim's families.
Berkowitz is serving 6 consecutive, 25-years-to-life sentences for killing 6 people since 1976.
A prison spokesman says they are trying to determine whether it can
seize any donations.
