While Jesus Cabrera Molina has not yet been charged in the death of Officer Daryl Raetz, he is in custody on separate drug charges, the paperwork shows.
Molina was arrested around 1:15 p.m. Sunday during a traffic stop near Thompson Ranch Road and Grand Avenue in Surprise.
The records show Molina was pulled over by an officer who recognized that the 24-year-old's SUV matched the description of a vehicle involved in the deadly hit-and-run from early Sunday.
According to the court paperwork, Molina's vehicle was found to have significant damage to the center grill and hood, similar to the vehicle seen fleeing the crash that left Raetz dead near 51st Avenue and Cambridge.
Detectives were also able to match a part left at the hit-and-run scene with "the missing areas" on Molina's SUV.
While speaking with and conducting a search of Molina during the stop, a small bag of white powder fell to the ground. The 24-year-old reportedly admitted that the substance was cocaine, and was taken into custody.
Court records show Molina also admitted that he is an undocumented immigrant.
Molina is the registered owner of the vehicle, and his father reportedly told police his son is the only driver. Police are working to confirm who was driving the vehicle at the time of the deadly accident.
Officer Raetz was killed as he wrapped up a DUI traffic stop.
An account has been opened for Officer Raetz's family. The account is at any Midfirst Bank - Hands Across Arizona for the benefit of Daryl Raetz.
