ST. PETERSBURG — Police arrested a 22-year-old man in the fatal shooting of a 41-year-old man on his way home from work early Saturday morning.

According to St. Petersburg police, Malcolm J. DiPina of Sarasota was driving with friends north on Fourth Street S about 12:25 a.m. Saturday when Scott R. Franklin pulled up next to them in his car. DiPina and his friends, who were split into two cars, got in an argument with Franklin because one of the cars had cut off the other.

The cars went west, then turned north onto Sixth Street S, where Franklin stopped his car beside DiPina's car at a red light at Fifth Avenue S, near Johns Hopkins All Children's Hospital. The verbal altercation escalated and DiPina shot Franklin, police said.

DiPina and his friends fled the scene. They returned later to speak to St. Petersburg detectives.

Investigators arrested Di­Pina on Saturday evening on a manslaughter charge. He was booked into the Pinellas County Jail and was released on bail about 7 a.m. Sunday, according to jail records.
