A young Texas father has been found guilty today of badly injuring his infant daughter by putting her in a microwave.

The jurors rejected 20-year-old Joshua Mauldin's argument that he was insane. They will now consider evidence on how to sentence him. He could face anything from probation to life in prison.

Mauldin claimed he was going through a psychotic episode when he put two-month-old Ana in a microwave for 10 to 20 seconds in May.

But prosecutors said Mauldin knowingly hurt his daughter because he was angry about being stuck in a loveless marriage.

Ana was badly burned and part of one ear had to be amputated. Officials say she is still receiving treatment, but is doing well.
