LANSDALE, Pa. -

A recent drug bust has sent three to prison, including a woman and her son.

The Lansdale Police Department received numerous reports about drug dealing of crack cocaine and marijuana during 2010 and 2011, so members of the Montgomery County District Attorney's Municipal Drug Task Force and Narcotics Enforcement Team started an investigation. This targeted two properties in Lansdale.

Police said the investigation of 34 W. Hancock St. showed that street dealers were coming to this address to obtain their cocaine and sell it around Lansdale. Crack cocaine was also cooked or manufactured on the property. Residents Robin Green, 41, and her son, Marc Wallace, 20, were identified as potential suspects, police said.

Police surveillance of the property was conducted along with purchases from both suspects.

On Saturday at 6 a.m., officers executed a search warrant of the property, which turned up suspected marijuana and cocaine, along with digital scales, hundreds of small zip-lock bags, crack pipes, razor blades, copper wadding and $465 cash.

Two minor children related to Green and Wallace, ages 7 years old and 7 months old, were there during the seizure and were turned over to relatives.

Green and Wallace were arrested on charges of criminal conspiracy, felony manufacture/deliver/possession with intent to deliver a controlled substance, three counts of possession of a controlled substance, possession with intent to use drug paraphernalia and endangering the welfare of children.

Both were arraigned and taken to Montgomery County Correctional Facility after failing to post bail of $75,000.

Another location of interest was 39 E. Sixth St., in the first floor apartment. Police said activity usually took place late at night where visitors stayed only for a brief amount of time. A confidential informant told officers that a resident named Darrell Fernandez, 27, was involved in illegal drug sales.

Police began surveillance of the residence and observed subjects entering and leaving a short time later.  Police arranged controlled purchases from Fernandez out of his apartment.

On Saturday at 8:45 a.m., officers executed a search warrant of this property and seized suspected marijuana, pipes, ledgers indicating a recorded history of drug sales and profits, and $626 in cash.

Officers arrested Fernandez on charges of felony manufacture/deliver/possession with intent to deliver a controlled substance, possession of a controlled substance, and  possession with intent to use drug paraphernalia.

Fernandez was arraigned and taken to Montgomery County Correctional Facility after failing to post bail of $25,000.
