Friends of Michaela said Walczuch was at the Jehovah’s Witness meeting on May 3 and that police had confirmed this.
But church elder Brother Teofilo Castela has said: "She was thrown out of the church more than a year ago and doesn't attend."
He added: “I haven’t been interviewed by the police. They haven’t been here.”
Another witness said, "I haven’t seen Michaela all year. She’s been thrown out."
Reportedly, Portuguese detectives have not bothered to test Walczuch's alibi by talking to any of the Jehovah’s Witnesses in Lagos, near Praia da Luz.
