By AZ law they are only required to give a receipt. The warrant has to be signed and returned to the judge that issued it.
They did not read her her rights though they would not let her go. They interrogated her for a long time before they read her her rights and then they reinterrogated her.
That's only an issue if what she said is going to be used in a criminal proceeding against her. She could always have asked to be let go, or to not say anything.
They were proud of unloading their weapons and interested in “finishing what they started.”
That's your editorial opinion. Finishing what you started is a common thing to say.
What in God's name are you talking about? A receipt before they serve a warrant, after they serve a warrant? A warrant is a warrant.....did she get a damn warrant or not?
She did ask to be let go so she could check on her child or to speak to her mother in law who came to pick up the child. I don’t think it will be an issue.
At the point she was detained, and no longer free to leave, she was read her rights by the homicide detectives. The transcript of their interview has an extensive Miranda discussion, both in English and Spanish. She professed not to understand, and the warning was re-explained repeatedly.
Nevertheless, if you read it, you’ll see the knowing waiver issue would be a close call in the event of a criminal prosecution.
