Mala Manwani, 65, and her son Rishi Manwani, 32, were found shot to death inside their Aldie, Virginia, home after deputies checked on Mala when she missed work. The bodies were located in separate areas of the house; both had sustained multiple gunshot wounds. Investigators said there were no signs of forced entry and thought the attack was targeted. Early in the inquiry detectives learned Rishi had been selling oxycodone from the residence, and investigators considered that activity a possible motive.

Brian K. Welsh, 38, of Herndon, who knew Rishi as a friend and customer, was arrested in March 2018 after casings at the scene were initially linked to a pistol he owned. Those murder charges were dropped in August 2018 when ballistics testing showed bullets taken from the victims were not fired from Welsh’s gun. Welsh remained a suspect as the probe continued.

Subsequent testing and expert testimony in firearms, DNA and cell phone forensics were used at trial, and jurors later returned guilty verdicts. Who has information about the Manwanis or the events in Aldie on January 29, 2018?
