AUSTIN, Texas -

(AP) - The case of a Texas woman is raising questions about whether parents convicted of kidnapping their own children in custody disputes should be automatically registered in the state as sex offenders.

Suzanne Kearns was convicted of aggravated kidnapping after taking her son to Mexico. Kearns was freed from prison in 2010 but must register as a sex offender until 2020. 

Since 1999, child kidnappers in Texas must register as sex offenders for 10 years after their prison release. But 34 other states exempt parents who take their children in custody disputes.

The Austin American-Statesman reports ( ) the Texas Court of Criminal Appeals last month rejected Kearns' appeal to be removed from the registry.

But two judges submitted an opinion questioning the inclusion of child-custody kidnappings in the sex offender registry.
