Revealed: Honor student, 17, smiled and laughed before fatally stabbing 'love rival' classmate, 16, over a boy

The 17-year-old Detroit-area girl accused of killing a classmate in school was laughing as she chased the victim and stabbed her in the chest and back, authorities said Friday as they filed a first-degree murder charge.

Tanaya Lewis was arraigned in Warren District Court, two days after 16-year-old Danyna Gibson was stabbed with a steak knife in a classroom at Fitzgerald High School. Police said there was animosity between the straight-A students over a boy.

The case is 'very unfortunate, all the way around,' defense attorney Mark Brown said after the hearing.

Lewis appeared in court via video from jail and was denied bond. Her parents watched from the courtroom gallery.
