A Chicago man accused of murdering his 9-year-old daughter was formally arraigned Wednesday.

Prosecutors charged Richard Lyons in January after investigators say forensic evidence linked him to the crime.

Lyons claims he found his daughter, Mya, stabbed in the alley near his South Side home.

The father pleaded not guilty. His next court hearing is scheduled for next month.
