The owner of pit bulls that dragged a 4-year-old Detroit boy from his mother and killed him is returning to court for a key hearing.

A judge must decide whether there's enough evidence to send Geneke Lyons to trial on second-degree murder and other charges. A hearing is planned for Tuesday.

Xavier Strickland was walking with his mother in Detroit when they were attacked by pit bulls Dec. 2. Police had to shoot the dogs to free the boy's body. Three were killed; a fourth was euthanized.

Prosecutor Kym Worthy calls it a "harrowing example of irresponsible pet ownership."

Defense attorney Francisco Villarruel says the dogs were dangerous, not the owner.
