Dequan Ardoin was 25 when he was fatally shot in Houston on October 13, 2017. The attack occurred about 1:50 p.m. on the 6800 block of London and was one of several casualties in a multi-victim shooting.

Police say four armed suspects arrived in a blue Mazda, opened fire, then abandoned that vehicle and carjacked a dark green Kia Sedona at gunpoint to continue their escape; the car’s driver and her infant were not harmed. Two suspects, DeAndre Watson and Mertroy Harris, were arrested soon after the shooting in 2017. In 2019, authorities identified and charged two more individuals, Marquis Erskin and Marcus Christopher. All four faced murder and organized crime charges as the Houston Police Department continued its investigation and sought public help, with Crime Stoppers offering incentives for information.

Does anyone have information about the 6800 block of London on October 13, 2017, or about movements of the blue Mazda or dark green Kia Sedona that afternoon?
