A Fort Dodge teenager has pleaded not guilty to charges that she allegedly aided and abetted another teen during a May 2 shooting homicide in downtown Fort Dodge.

According to court records, Haydin Mapel, 16, filed a written plea of not guilty on Friday and demanded her right to a speedy trial. She was arrested and charged on May 4 with aiding and abetting first-degree murder, a Class A felony; and aiding and abetting attempted murder, a Class B felony.

The May 2 shooting reported in the 100 block of North 10th Street in Fort Dodge left 18-year-old Patrick Walker dead and 20-year-old Silas Hall injured.

Hours following the shooting, an arrest warrant was issued for 17-year-old Davonquae Jyshon Pettigrew. Pettigrew was apprehended on Saturday in Davenport.

According to a motion filed by Mapel’s attorney for a reverse waiver to Juvenile Court jurisdiction, the state is alleging that Mapel drove a vehicle “containing a passenger that fired shots in response to shots being fired at the vehicle, including striking the driver’s door” where Mapel was sitting.

In the motion, attorney Judd Parker noted that there is “good cause” to waive the case to Juvenile Court because the defendant is 16, does not have a significant criminal or delinquent history and is able to be rehabilitated prior to turning 18.

On a May 10 order, District Court Judge Adria Kester ordered that a juvenile court officer provide a report regarding whether Mapel should be transferred to Juvenile Court, and a hearing will be held after the report is filed.

As of Tuesday, a hearing had not yet been scheduled.

Kester did accept Mapel’s written plea of not guilty on Tuesday and has tentatively scheduled a trial for July 25.
