Harvard University law professor and celebrity defense attorney Alan Dershowitz is advising a former pharmaceutical executive charged with killing her autistic 8-year-old son in a New York luxury hotel.
Dershowitz joined Gigi Jordan and her other lawyers at a court appearance Tuesday. Attorney Ron Kuby says Dershowitz was there as a "constitutional consultant." The lawyers won't elaborate on his role.
Jordan has pleaded not guilty to murder in son Jude Mirra's February 2010 death.
Authorities say she wrote a letter saying she planned to kill herself and her son. They say she gave him a deadly overdose of prescription pills and apparently took some herself.
Dershowitz' clients have included Mike Tyson and O.J. Simpson.
Jordan made a fortune in the drug industry before leaving it to devote herself to her son.
