FLORISSANT, MO (KTVI) - ST. LOUIS COUNTY, MO (KTVI) - The son of St. Louis County Executive Charlie Dooley has turned himself into police. Thirty-seven year-old Phillip Goodwin is suspected of robbing 18 convenience stores in the St. Louis area, all within the past month.

In these robberies, police say Goodwin did not conceal his face, which made it easier to identify him. Nearly every day, from September 17th until October 8th, Florissant police say Goodwin robbed gas station convenience stores throughout the St. Louis area. In each of these, police say Goodwin had a similar modus operandi: he would walk in, acting like a normal customer, and go up to the counter, pretending to buy small items. In several of these cases, he asked for Black and Mild's.

Florissant Police Officer Andy Haarmann says, "When the clerk rang up the item and opened up the cash register, the individual would push away the clerk, grab whatever he could out of the cash register, then run out of the store."

It was the most recent robbery of a Circle K in Florissant that finally got Goodwin caught. Haarmann the clerks were able to get a vehicle description. Even though the suspect got away, officers did catch the vehicle's license plate and registered owner's information.

Haarmann explains, "That started the investigation. We were able to positively identify the suspect through a photo lineup with the clerks at the Circle K gas station. Several other of the jurisdictions that were working similar robberies were able to then use our information to positively identify the suspects in their robberies."

Other area police departments linked physical evidence left at the scene to Goodwin. At 11 o'clock Wednesday night, Goodwin turned himself in.

The 37 year-old has previously served several years in prison for felony stealing, resisting arrest, and the unlawful use of a weapon.
