The man accused of killing University of Utah student MacKenzie Lueck has been charged with aggravated murder and aggravated kidnapping days after police found her body in Logan Canyon.

Ayoola Ajayi, 31, faces four felony counts, including second-degree felony obstruction of justice and third-degree felony desecration of a body, in the high-profile case that has captivated the state and the nation since Lueck disappeared on June 17.

The charges, filed Wednesday by Salt Lake County District Attorney Sim Gill, say Lueck died of blunt force trauma to her head. Gill said her body was found with her arms bound behind her back by a zip tie and rope.
