On the afternoon of March 18, 2015, a rolling gunfight along the westbound lanes of Interstate 44 in St. Louis ended with two 21-year-olds dead. Derrick Roberts and DeJuan Etheridge were found with fatal gunshot wounds in and just outside a white Dodge Charger that stopped in the LaSalle Park neighborhood. Investigators recovered about 30 shell casings from the I-44 exit ramp to Hampton Avenue.

Police reported finding cash and heroin inside the Charger, and an off-duty officer who witnessed the exchange followed the vehicles briefly. Investigators said a dark-colored sedan was involved and that a third person may have been in the Charger and left after it stopped. No arrests or suspects have been publicly announced, and the case remains unresolved.

If anyone has information about the vehicles, the people in the Charger, or that stretch of I-44 that afternoon, please share what is known.
