Robert Durst, 76, is on trial in Los Angeles for the murder of his friend Susan Berman.
Durst, who made a fortune in real estate, has been held in a Louisiana jail since being arrested in March.
A federal case in Louisana is still pending for similar charges, as are charges of murder in California.
Durst was acquitted of the murder of his neighbor Morris Black.
Charatan is a leading investor in a company that owns dozens of properties in New York City.
Durst's attorneys have sought to expedite his extradition to Los Angeles County on a murder charge.
"That song is just about a horny werewolf," not about "killing anybody," Mark Oliver Everett says.
Robert Durst also once beheaded a human, but was acquitted of murder charges.
Durst may have been booted from his namesake company, but his real estate connections live on.
It could help the defense build an insanity plea.
Robert Durst, subject of HBO documentary "The Jinx," is arrested in New Orleans on a first-degree murder charge one day before the last episode is set to air.
