Found out that arrests have been made in this case, sadly one of those arrested is Ida's own daughter, 47-year old Gabrielle Houston, and her friend, 45-year old Kareem Grant.
It seems collecting on ida's life insurance policy was the alleged motive.
P.S. Please note the connotation in the title of this thread will be SOLVED since the case is solved as far as law enforcement/prosecutors are concerned. Gabrielle Houston and Kareem Grant will still go on trial and are considered innocent until proven guilty in a court law.
