Wichita ? The Kansas attorney general’s office says a man suspected of killing a Kansas college student who led a secret life as an Internet porn model is appealing his extradition from Mexico.

Ashley Anstaett, spokeswoman for the Kansas attorney general’s office, says a higher court in Mexico will now review the case against Israel Mireles. That could take an additional three to four months.

Mireles was arrested in December at a relative’s home in Melchor Muzquiz, Mexico. He has been held pending extradition.

Mireles is charged with capital murder, rape and aggravated criminal sodomy in the death of 18-year-old Emily Sander. She was last seen alive Nov. 23 leaving a bar with a man police identified as Mireles.

The disappearance of the Butler Community College student drew nationwide attention after the discovery that she also was an Internet pornography model named Zoey Zane.
