DAYTON, Ohio -- A 13-year-old Ohio boy died of a suspected heroin overdose, and his father has been jailed in a previous drug-related case, according to authorities. 
 
 Nathan Wylie’s father and a co-worker frantically carried the unconscious boy on March 28 from a mechanic’s lot to a fire station next door, CBS Dayton affiliate WHIO reports. They indicated that Nathan got into his father’s drugs. A police report said medics administered four milligrams of Narcan without any response before Nathan was taken to a hospital because he was not breathing. 
 
 The boy died Saturday at a hospital. Police said Monday they were interviewing witnesses to determine exactly what kind of drugs the boy accessed and how. 
 
 “We don’t know what kind of drugs,” Dayton Police Lt. Andrew Booher said. “We’re still waiting for a (toxicology) report from the coroner’s office.” 
 
 The boy’s father, 40-year-old Robert Wylie, was arrested on suspicion of child endangerment. While he was technically released March 30 in the overdose case, WHIO reports, he remained jailed in connection with a December traffic stop in which he was arrested for drug possession. A December report shows that police said they found Wylie with a needle, syringe, heroin and crack cocaine during a traffic stop of his girlfriend, Tina Davis. 
 
 A message seeking comment was left Tuesday for his public defender in that case. 
 
 Dayton police had previously found drug paraphernalia in the boy’s home, according to WHIO. Police reports indicate that in February last year, another minor who then lived in the home sent a relative a picture of a bag of white powder and a razor blade on a plate. The picture made its way to law enforcement. 
 
 “The razor had white residue on the razor’s edge,” a police report from Feb. 8, 2016 said, adding that Montgomery County Children Services was contacted. “Next to the plate was a metal crack pipe with a burnt end along with a cut straw.” 
 
 A police officer later found two crack pipes and a capped needle in the home, according to the report. 
 
 The February 2016 report indicates Dayton police had arrested Wylie and his girlfriend, Davis, for child endangerment and possession of drug paraphernalia and drug abuse instruments. 
 
 Wylie’s December case is pending in court. Court records show he has multiple misdemeanor drug cases dating back to 1998. 

 The father and another man took the unconscious boy to the fire department Thursday. A witness told a medic that the boy's father "was on drugs and the boy got into his stuff," the police report reads. 

 Dayton police previously found drug paraphernalia in the home of 13-year-old Nathan Wylie, the boy who died Saturday of a suspected heroin overdose. The Montgomery County Coroner’s Office said Nathan died at 11:56 a.m. April 1. 
 
 Police reports indicate that in February 2016, another minor child who then lived in Wylie’s Valley Street home sent a relative a photo of a plastic bag of white powder and a razor blade sitting on a plate. The photo made its way to law enforcement. 
 
 “The razor had white residue on the razor’s edge,” the Feb. 8, 2016 report said, later adding that Montgomery County Children Services was contacted. “Next to the plate was a metal crack pipe with a burnt end along with a cut straw.”

 The boy’s father, Robert B. Wylie, 40, is in Montgomery County Jail on a $100,000 surety bond for a December 2016 case. Dayton Municipal Court officials said on Monday that Wylie technically was released March 30 in the overdose case. 
 
 A report from Dec. 17, 2016 shows police said they found Wylie with a needle, syringe, heroin and crack cocaine during a traffic stop of Wylie’s girlfriend, Tina Davis. 
 
 Davis, 37, was arrested Sunday night on suspicion of drunk driving, possession of drugs and physical control and was booked into the jail. 
 
 On March 28, Wylie and a roofing business co-worker showed up from a repair shop next door and were banging on the garage door at a fire station along with Nathan, who was unconscious, according to the police report. The co-worker said Wylie was on drugs and “the boy got into his stuff.” 
 
 The report said medics administered four milligrams of Narcan without any response before he was taken to Miami Valley Hospital because he was not breathing. An officer served Wylie an indictment warrant and added a child endangering charge.

 Dayton police said Monday they were interviewing witnesses to determine how Nathan got access to drugs. “We don’t know what kind of drugs,” Dayton police Lt. Andrew Booher said. “We’re still waiting for a (toxicology) report from the coroner’s office.” 
 
 Booher said one child was removed from the house as a precaution and that charges were likely after consultation with the prosecutor’s office. 
 
 The February 2016 report indicates Dayton police arrested Wylie and Davis for child endangerment and possession of drug abuse instruments and drug paraphernalia. 
 
 A Dayton officer wrote that he looked around the residence for proof that the photo of possible drugs was real. When the officer saw a knife that also was in the picture, he found in a dresser drawer two crack pipes and a capped needle. 
 
 “After finding these items, Tina told me to stop searching and I did,” the officer wrote, later adding that a child endanger packet was formed.

 Davis was found guilty of misdemeanor child endangering and given a suspended 180-day jail sentence and ordered to undergo a life skills class. Her probation later was revoked, according to court records. 
 
 The December 2016 report shows Wylie was arrested after police stopped a car driven by Davis near South Broadway Street and West Stewart Street, an area “known for high drug activity,” according to the officer. 
 
 The report said Nathan was in the vehicle when officers asked Wylie to exit the vehicle. Wylie told officers before a pat-down that in his pocket he had a “rig” — a hypodermic needle and syringe. 
 
 Officers also seized more needles, a green bottle with what appeared to be heroin caps and a cigarette box of what Wylie said was crack cocaine. An officer wrote that, “Wylie stated that his son Nathan was allowed to stay with Tina and she agreed to it.” 
 
 Wylie’s December case is pending in Montgomery County Common Pleas Court. Municipal court records show Wylie has multiple misdemeanor drug cases for drug abuse, marijuana possession and drug abuse in a park dating back to 1998.

 The girlfriend of the man whose 13-year-old son died of a suspected heroin overdose from his father’s stash received a break in court, according to Dayton Municipal Court records. 
 
 Tina M. Davis, 37, tested positive for drugs and violated her probation from a 2016 child endangerment case but only served about a month of a six-month sentence imposed because a judge wrote that it was in the “interests of justice.” 
 
 Davis is the girlfriend of Robert Wylie, 40, whose son Nathan died Saturday at Dayton Children’s Hospital from an overdose, according to police reports.

 A Montgomery County Children Services spokesman said case files are confidential, but that the agency was referred to Wylie’s Valley Street address. 
 
 “We have had a case open with this family,” spokesman Kevin Lavoie said Tuesday. “We have taken steps to ensure the safety of Nathan Wylie’s sibling in the wake of this horrible tragedy.” 
 
 In 2016, Davis faced a first-degree misdemeanor child endangering charge when instruments of drug abuse were found in the home where four children then lived.

 A letter from Dayton city assistant prosecutor Joshua Shaw said the state planned to use evidence of prior drug use by Davis. “In this matter , the State will introduce into the defendant’s prior drug use to prove her motive to commit forgery and theft crimes.” 
 
 A plea was reached and Davis was given a 180-day suspended sentence and ordered to undergo drug and alcohol counseling along with life skills counseling. 
 
 A letter from her probation officers said Davis only reported twice in a period of several months “due to various excuses.” The letter said Davis tested positive for cocaine, opiates, OxyContin and Benzodiazepines, didn’t enroll in parenting classes and failed to complete an alcohol and drug evaluation.

 “This officer is tired of Ms. Davis’s countless excuses as to why she is not in compliance,” the officer wrote. “She is not taking the privilege of probation seriously.” 
 
 In October 2016, Davis’ probation was revoked for violating terms and she was sentenced to 180 days, according to court documents obtained by this news organization. 
 
 On Nov. 22, 2016, Dayton Municipal Court Judge Daniel Gehres terminated the case and wrote that it was in the “interests of justice” to do so. Further explanation of Gehres’ decision was not written in court documents.

 A Dec. 17, 2016 Dayton police report shows officers said they found Robert Wylie with a needle, syringe, heroin and crack cocaine during a traffic stop of Davis. 
 
 Wylie’s December case is pending in Montgomery County Common Pleas Court. Municipal court records show Wylie has multiple misdemeanor drug cases for drug abuse, marijuana possession and drug abuse in a park dating back to 1998. 
 
 Davis was arrested Sunday night for an unrelated incident of suspected drunk driving, possession of drugs and physical control and was booked into the jail. Formal charges have not been filed.
– Fire officials found Robert Wylie banging on the door of the fire department, holding his 13-year-old son's unconscious body. But the doses of Narcan they administered couldn't save the teen. Nathan Wylie died of a suspected heroin overdose on Saturday, four days after he was taken to a Dayton, Ohio, hospital, reports the Dayton Daily News. Officials say Nathan had access to drugs because his father is an addict. Wylie had already been arrested for child endangerment after another minor who lived at Wylie's home sent a relative a photo of white powder, a razor blade, and a crack pipe in the home in Feb. 2016, police say. He was later arrested for drug possession after he was found with heroin and crack cocaine during a traffic stop in December, with Nathan in the backseat, police say, per CBS News. It isn't clear why Nathan remained at the residence. A rep for Montgomery County Children Services tells the Daily News only that there was "a case open with this family" and that Nathan's sibling was removed from the home following Nathan's death. After Nathan was taken to the hospital—a witness told officials Wylie "was on drugs and the boy got into his stuff," per WXIX—Wylie was again arrested on suspicion of child endangerment. The 40-year-old was released in that case on Thursday. However, he remains in Montgomery County Jail in relation to the December case. Wylie's live-in girlfriend, Tina Davis—who was previously charged in the February case—faces new charges of drunk driving and drug possession after an arrest on Sunday.
