Costa Rica’s drug control police unit raided the home of an alleged mother-daughter drug dealing duo Friday, bringing the number of family-run narco rings they have busted since the start of last year to 311, reported the Public Security Ministry.

The team presumably led a drug dealing operation out of their home in a neighborhood in Sixaola, Talamanca, in the Caribbean province of Limón

Police were tipped off on the family’s alleged criminal activities by anonymous reports made via the 1176 line – a free, 24-hour line to report of suspicious or criminal activities.

From 2016 to August 2017, Costa Rican police report they have broken up 1,242 illegal drug organizations in the country, of which 999 are local, 243 are international, and 311 family operations.

The women detained in this latest bust are Talavera (46) and Montiel (19). The mother-daughter team apparently sold drugs round the clock out of the house where they lived in a residential development called Ivannia in the district of Catarina de Sixaola. If convicted, the women could face up to 20 years in prison, said police in a statement.

The women’s home is located 300 meters from a school in Catarina de Sixaola, said police reports.

Neither Talavera nor her daughter have any previous police records, convictions or cases filed against them. Police seized small amounts of cash, marijuana, crack and cocaine, and also found an electronic scale and drug-making utensils and supplies.

So far in 2017, police have seized a total of 155,824 doses of crack, and 3.5 tons of marijuana in its dried and cut form (ready for sale/use), said the public security ministry.
