"My heart is broken," said Althea Lee, Malik Lee's mother. DC Police found Malik Lee's body along Cincinnati Alley off Columbia Road NW near 17th Street in the Adams Morgan neighborhood on Dec. 8. He had been stabbed. "He was very loving. He was so much fun in my family," Althea Lee told the crowd at the vigil. Takoma Park mother mourns son who died after being stabbed in DC Malik Lee taught at Highland Elementary School in Silver Spring. Parents of his students joined others at the ceremony.
