Yongela Nelvik Ward, 22, was arrested March 22 for the deadly hit and run collision that occurred the night before, authorities said.
The victim was struck and killed near Queen Creek Road and Power Road shortly before 8 p.m, while biking to his home, which is near the crash scene.
Ward is accused of fleeing the scene, police said.
She and her vehicle were found after police received a tip as to its whereabouts.
Because Ward is pregnant, she was not booked into jail.
