With no explanation, chose the best option from "A", "B", "C" or "D". to search the house, and, while appellant was handcuffed in the back of the patrol car, the officers told him that if he did not consent, his mother and young son would be required to vacate the house while the officers secured the residence, despite the officers having no basis for doing so. After this threat was made, appellant spoke to his mother; appellant then agreed to sign the written consent to search. The officers’ threats to remove appellant’s family from the residence are what lead appellant ultimately to consent to a search of his residence. Such antagonistic action by the police against a suspect’s family is a factor which significantly undermines the voluntariness of any subsequent consent given by the suspect. See United States v. Ivy, 165 F.3d 397, 403-04 (6th Cir.1998) (<HOLDING>); United States v. Bolin, 514 F.2d 554, 560-61
