PHOENIX (AP) — A mother from Arizona has a Wednesday court appearance where her family said lawyers will question key witnesses in an attempt to prove she did not smuggle marijuana on a passenger bus.

The arrest of Yanira Maldonado, 42, has prompted outrage in the U.S. among politicians and her family members, who say she was set up when her bus was stopped at a military checkpoint last week and authorities found nearly 12 pounds of marijuana under her seat. She was immediately sent to a Mexico prison.

She and her husband, Gary Maldonado, said they were returning from the funeral of her aunt at the time of the arrest. Gary Maldonado says his wife was framed and that authorities originally demanded $5,000 for her release. The husband was initially suspected of smuggling, but he was later released.

The arrest has received national attention and been a fixture on TV networks with its nightmare scenario of a mother of seven being caught up in a drug case and sent to prison in a judicial system that has long struggled with corruption.
