Police say, Monica Sementilli enlisted the help of Baker to plot and carry out the murder of her husband.  A claim her attorney flatly denies.
"My client adamantly denies any involvement in the murder of her husband and we are hopeful when all the facts come out she will be totally exonerated" said, Leonard Levine, Monica Sementilli's attorney.

The vehicle was later recovered, police announced three days after Sementilli was found dead.

"It was things we were able to put together on the outside that proved some inconsistencies in her statements which seemed to stay the same through out the course of the investigation. " said Hayes. 

Sementilli was an established hairdresser who served as Vice President of Education for Wella, the salon professional division of Procter and Gamble, according to Salon Today magazine.

Monica Sementilli and the male suspect were both being held without bail, according to officials.
