ST. LOUIS — A second man has been charged in the fatal shooting of a 15-year-old boy in south city.

According to probable cause statements, the new suspect—Brian Lee Potter—goaded the first suspect into fatally shooting 15-year-old Sentonio Cox.

Potter and Joseph Renick are accused in the crime that happened on Aug. 25 in the 7300 block of Vermont Avenue.

According to court documents, Potter and Renick came outside of a home to confront Sentonio and another person. Potter aggressively walked toward Sentonio, forcing him across the street, up a hill and into a vacant lot. Renick was behind Potter while he walked toward the teen.

Sentonio’s hands were raised up as he backed away from the men, the court document stated.

His mother believes he was cutting through Renick's yard. A witness directed 5 On Your Side to an isolated 'do not enter' sign placed near Renick's property.
