FORT LAUDERDALE (CBS4) – The South Florida teen charged in the death of a man who was hit while mowing a family member’s lawn went to court Wednesday to change his plea. Daniel Ferguson, now 18, plead not guilty.

Investigators say Ferguson is responsible for the death of 67-year-old Ronald Newel who was struck and killed by a car while mowing his sister’s lawn at 3611 NW 9th Court in May of 2010. Ferguson, 17 at the time of the hit and run, allegedly left the scene.

A passenger in the car, 17-year-old Jakari Murray, also died as result of injuries he suffered in the crash.

Ferguson reportedly told police some balloons in the car blocked his vision which caused him to swerve and hit Newel.

Ferguson is charged with two counts of leaving the scene of an accident with death, two counts of driving without a valid license with death, and leaving the scene of an accident with property damage .
