A New Jersey man has been charged with first-degree aggravated manslaughter and endangering the welfare of a child for the death of his 12-year-old nephew, NBC News reported. Last week, prosecutors charged Troy Nokes, 35, with 28 charges after the overdose death of his nephew. Nokes allegedly told his nephew to clean up drug items containing fentanyl the Gloucester Township and Camden County Prosecutor’s Office said in a press release NBC News reported.

Along with manslaughter, Nokes is charged with first-degree strict liability drug-induced death, first degree maintaining a controlled dangerous substance production facility, employing a juvenile in a drug distribution scheme, witness tampering, tampering with evidence, hindering apprehension and aggravated assault, among other charges, reads the release, according to NBC News.

Police allege he picked up the drugs without gloves the weekend before he passed away. Eight days later, witnesses discovered the 12-year old unresponsive on his school bus in Gloucester Township, according to police.

“It angers me quite frankly, this 12-year-old who is just going to school is exposed to this-these drugs that a 12-year-old should not be exposed to” Police Chief David Hawkins said. An autopsy report said the 12-year-old died because of a fentanyl overdose. Nokes has been accused of running a “controlled dangerous substance production facility” in his home where he lived with his nephew.

Consuming only 0.002 grams of the deadly opioid can have fatal consequences, according tothe National Center for Drug Abuse Statistics, The New York Posts reported.  Nokes’ girlfriend Joanna Johnson also faces charges for tampering with evidence and protecting Nokes from arrest NBC Philadelphia reports.

Chief Harkins told the news station that the child’s caretaker and grandmother are “devastated.”

“And she is losing a family member now who’s going into the criminal justice system to be prosecuted. But more importantly, she’s lost her 12-year-old grandson,” Harkins said.
