State police have arrested a woman who filled her 18-month-old daughter's sippy cup with beer and gave it to her in front of undercover narcotics agents, according to court records.

State police Lt. Juan Martinez said Monday that undercover agents with the Region III Narcotics Task Force were at 21-year-old Virginia Neel-Blaker's home in Ojo Caliente to buy drugs from her and her husband, James Blaker.

The agents saw her give her daughter a sip of beer from a can. Then she allegedly filled up the girl's sippy cup with beer and gave it to the toddler to get her to sleep, Martinez said.

"The trafficking case took a back seat to abuse of a child," Martinez said. "It was very disheartening for them to see that happening to a child."

Neel-Blaker has been charged with prostitution, child abuse, distribution of marijuana and two counts of conspiracy to traffic heroin.

James Blaker, 37, was charged with three counts of trafficking heroin, distribution of marijuana, child abuse and promoting prostitution.

The undercover agents had bought heroin and marijuana at the home on three separate occasions. Neel-Blaker also offered twice to have sex with them for $100, a search warrant said.

Martinez says the child was handed over to the state's Children, Youth and Families Department.

The couple is being held at the Rio Arriba County jail in Tierra Amarilla.
