GRAYSLAKE, Ill. -- Two Illinois parents were in police custody Tuesday after heroin and hypodermic needles were found in their three-year-old son's crib, the Chicago Tribune reported.

Officers in Grayslake, Ill., about 50 miles north of Chicago, went to the home of 27-year-old Jason Tomblin and 23-year-old Ashley Merz on June 7 to arrest Tomblin on a warrant.

When officers searched the bedroom shared by Tomblin, Merz and their son, they found eight syringes, baggies containing a white residue, marijuana pipes, unidentified pills and other drug paraphernalia, Grayslake Police Commander Matt McCutcheon said.

Some of the items officers found, including some of the syringes, were in or around the three-year-old boy's crib, according to the report.

The residue in the baggies later tested positive for heroin.

Merz was arrested on charges of possession of a controlled substance, possession of drug paraphernalia and obstructing justice.

Tomblin was also arrested on the warrant for failure to appear in court on charges of obstruction of justice, destroying evidence, knowingly damaging property and theft.

Both were being held in jail in lieu of bond Tuesday. Their son is still living at the home with his grandmother, McCutcheon said.
