The police, answering a complaint about noise, arrived at Sam's apartment and found Sam's wife dead on the living room floor. One of the officers turned to Sam and asked, "What happened?" Sam replied, "She was a bitch and I took care of her." At Sam's trial, his statement should be ruled
admissible, because the statement was part of the res gestae.  admissible, because the statement was made at the scene, was essentially volunteered, and was not a product of a custodial interrogation.  inadmissible, because the statement is ambiguous and not necessarily incriminatory.  inadmissible, because Sam was effectively in police custody and should have been given the Miranda warnings
