Their history with Clark County Child Protective Services stretches back to 2008. Las Vegas parents Donald E. Brown and Melissa D. Lawrence received 10 visits from CPS staff investigating allegations of possible neglect or abuse reported to the county’s child abuse hotline from 2008 to 2012, according to police and court records.
