Accused during police questioning in the disappearance of their missing daughter, the parents of 10-month-old Lisa Irwin want a new set of detectives to meet with them before they will agree to sit down for any further interrogation.
That’s the word from an attorney, Cyndy Short, who tells PEOPLE that her clients, parents Deborah Bradley and Jeremy Irwin, are on “an emotional roller coaster” as the search for Lisa hits Day 23.
Bradley, 25, and Irwin, 29, initially spent hours with police but have not consented to be questioned since Oct. 8, according to police, although they have remained available to investigators who are following up leads.
