Previously from WUSA9:
On WTOP this morning, Police Chief Cathy Lanier said police may have a lead in the case of missing siblings 4-year-old Wali McJunkin and 15-year-old Chantryce Johnson.
They have been missing since yesterday when Johnson picked up McJunkin at the Peaches 'N Cream Day Center located in the 300 block of Eastern Avenue, NE.
Police sources say Johnson has been listed as a runaway since September 22. She was spotted Wednesday for the first time when she picked up her little brother from daycare.
Police tell 9NEWS NOW that they have set up two command posts in the girl’s Southeast neighborhood and in the 300 block of Eastern Ave. NW at the daycare center.
The children’s mother, Gwen Johnson, tells 9NEWS NOW that she finds it difficult to eat or sleep with two of her children missing. She says the staff of Peaches 'N Cream Day Center should never have allowed a minor to take her son.
The mother of five children says she has tried everything she could to get help for the 15-year-old. She says, her daughter has run away eight times since December. She had her daughter in therapy prior to the disappearance.
