A 14-year-old charged with beating and robbing a 47-year-old man in October waived his preliminary hearing Wednesday.

Doryan Phynell Jackson of Davenport filed the waiver through his attorney, Barbara Maness, according to court records.

During a preliminary hearing, a judge decided whether there is enough evidence for the case to move forward. The judge doesn’t decide a defendant’s guilt or innocence.

Jackson will be arraigned Dec. 14. He will be tried in adult court as a youthful offender.

He faces charges of first-degree robbery, willful injury causing serious injury, and assault while participating in a felony.

Jackson also faces charges of second-degree burglary, conspiracy to commit a non-forcible felony, unlawful possession of a prescription drug, a serious misdemeanor, and possession of a controlled substance, also a serious misdemeanor, in unrelated cases.

Around 11 p.m. Oct. 12, Lester Norton was walking his bicycle on the Davenport bike path, the Duck Creek Trail Parkway, near Hickory Grove and Hillandale roads.

Jackson and co-defendant Christopher M. Shadrick, 13, knocked him over and tried to steal his bike, according to police.

When Norton tried to stand up, the teens began hitting and kicking him and stole his cellphone and sweatshirt, according to police.

Norton was taken to Genesis Medical Center-East Rusholme Street, Davenport; police were called to the hospital at 11:30 p.m.

He has since been released from the hospital.

Shadrick also will be charged in adult court as a youthful offender in connection with the incident and other unrelated cases.

He will be arraigned Dec. 7.
