FOUR HOMICIDES RELATED
All four murders took place in the Southeast Seminole Heights neighborhood of Tampa.
The F.D.L.E. and A.T.F. analysis of the fired cartridge casings recovered from all four scenes proved that the same firearm was used to shoot all four victims. The casings were further identified as being fired in a Glock .40 caliber handgun.
Around 2:38 p.m. on November 28th, a third witness approached a Tampa Police officer while the officer was at the McDonald's in Ybor City. The witness told the officer that an employee, 24-year-old Howell Emanuel Donaldson III, handed the witness a McDonald's food bag with a gun in it. Tampa Police officers checked the bag's contents and found a .40 caliber Glock firearm loaded with SIG brand Smith and Wesson ammunition.
The witness told police that Donaldson expressed his intention to leave the state.
Donaldson left the restaurant before the firearm's discovery, however, he returned to the Ybor City McDonald's shortly thereafter. When he returned, Tampa police detained him for questioning.
ABC Action News got exclusive video when Donaldson was taken in for questioning on Tuesday:
Donaldson agreed to meet at Police Headquarters to provide a statement regarding the firearm. When he spoke with police, they repeatedly told him that he had the right to leave and/or end the conversation. The arrest affidavit says that Donaldson gave consent to conduct a search of his car and cell phone as well as permission to examine his firearm at the F.D.L.E. laboratory.
Police say that Donaldson admitted to buying the Glock firearm and ammunition from Shooter's World on Fletcher Avenue in September. Donaldson further attested to the fact that he was the only one who had control of the Glock firearm since purchasing it.
Donaldson told police that he was unfamiliar with the Seminole Heights neighborhood, and did not have any association with anyone in the area, according to the arrest affidavit.
Cell Phone Locations
When police searched Donaldson's cell phone, it revealed storage of location data, known as "significant locations," which police say revealed an address in the 1300 block of East Frierson Avenue. The location data indicated only three days of recorded times and activities.
- October 9, 2017: Between 8:47 and 9:02 p.m.
- October 11, 2017: Between 8:18 and 8:42 p.m.
- October 19, 2017: Between 7:51 and 7:58 p.m.
During the ongoing investigation related to the pattern of the homicides, call detail records were obtained from AT&T. The records showed that within minutes of the murders on October 9, October 11, and October 19, Donaldson's cell phone was geographically associated with the AT&T cell tower providing coverage for the areas that include all the homicide locations.
Clothing Found in Car
When police searched Donaldson's car, they found clothing that looked similar to the clothes worn by the subject captured in surveillance video the night Benjamin Mitchell was murdered. The arrest affidavit states that police saw what appeared to be a blood stain on an article of clothing.
The F.D.L.E. comparison of the Glock firearm to the cartridge casings revealed that the cartridge casings, which were recovered in the first three murders, were fired through the Glock firearm. The casings in the fourth murder were unavailable for comparison but had been previously identified as being fired in the same firearm as the previous three. The recovered Glock firearm was loaded with a magazine containing five rounds of SIG brand Smith and Wesson .40 caliber ammunition.
Investigation into the firearm's purchase revealed that Donaldson purchased the firearm on October 3, 2017, and he picked it up on October 7. His purchase was in accordance with the mandatory wait period, which requires three days between purchase and delivery of a firearm, according to the Florida Constitution.
Receipts of purchase further revealed that Donaldson purchased a 20-round box of SIG brand Smith and Wesson ammunition on October 7.
