RIVIERA BEACH, Fla. -- Riviera Beach police are concerned about a mother who is missing along with her four children.

Police say Candice Sabonia Jackson and her children, who range in age from six months to four years-old, have not been seen since Sunday morning January 5.

Monday a concerned family member reported the family missing to an investigator with the Florida Department of Children and Families.

Police were contacted and got in touch with a boyfriend of Jackson. Detectives say he said he last saw Jackson Sunday morning around 7 a.m. when they rode with him to where he worked in Wellington.

Police say Jackson might be driving an older model green four-door Lincoln Town Car with a Florida tag (#L446FB).

Police say that Jackson's family considers her and the children endangered due to what they said was her addiction to powder cocaine and crack cocaine.

Investigators note that Jackson has been missing for long periods in the past, but never with her children.

Anyone with information should call Riviera Beach Police at (561) 845-4123 or Palm Beach County Crime Stoppers at 1-800-458-TIPS.
