Oct. 9: Officers find Benjamin Edward Mitchell lying near the bus stop at 15th Street and East Frierson Avenue about 9 a.m. with at least one gunshot wound, according to Tampa police. Mitchell is taken to a local hospital, where he later dies from his injuries.

Oct. 11: A city of Tampa employee discovers the body of Monica Caridad Hoffa, 32. just before 9 a.m. She is shot, but her body is hidden behind knee-high grass on city land near the corner of East New Orleans Avenue and North 11th Street. She was probably killed two days earlier.

The IHOP employee had never made it to work the day before. Her boyfriend had begun to agonize over why she wasn’t answering her phone.

Police Chief Brian Dugan said even before forensics returned showing the casings found at both scenes came from the exact same Glock, investigators knew they came from the same kind of gun.

Nov. 29: Donaldson is booked into Hillsborough County jail as details emerge of what evidence ties the Tampa man to the murders. A police report lists the same weapon, the same gun Donaldson asked a coworker at McDonald’s to hold for him, was used in each killing.

Police also say cellphone data puts him in the area of each killing. A hoodie that could be the one seen in the three released videos is found in his car.

Dugan says the nightmare is finally over.
