Police are continuing to seek the public’s help in finding two Richmond juveniles who ran away together Dec. 11, Richmond police Sgt. Bisa French said today. Shawn Graves, 14, and Megan Singh, 12, are believed to be either in Reno or Las Vegas and neither one has contacted their parents since they left, police said. Megan is an Asian-Indian girl with black hair and black eyes. She is 5 feet 3 inches tall and weighs about 110 pounds. Shawn is a white boy with blond hair and blue eyes. He is 5 feet 7 inches tall and weighs about 140 pounds. Both juveniles are considered “at risk” because of their ages and the amount of time that has lapsed since they left home, French said. The Richmond Police Department is working with the National Center for Missing and Exploited Children to try to find the juveniles. Anyone who has seen them is asked to call the Richmond Police Department at (510) 620-6675.
