Selwyn Days is facing his fourth trial on charges of murder in the death of elderly millionaire Archie Harris and his live-in health aide. The first two trials ended with hung juries.
His conviction in a third trial was overturned. And now, a key prosecution witness in the fourth trial has been accused of faking amnesia on the stand.
The witness, Cherlyn Mayhew is an ex-girlfriend of the suspect.
She has been accused of willfully refusing to answer questions by claiming she didn't remember.
Mayhew testified in an earlier trial that Days bragged about getting away with murder, according to the Journal News.
A contempt hearing for Mayhew started Friday and will continue Monday.
