A 3-year-old was uninjured when the child’s mother crashed her car off Glen Charlie Road Friday afternoon after overdosing on heroin, according to Wareham Police.

The driver, 34-year-old Jocelyn MacRoberts of Long Pond Road in Plymouth, was found slumped over the wheel near 144 Glen Charlie Road at approximately 2 p.m. after hitting bushes and a snowbank. Upon arrival, Sgt. Peter Flannery and Officer Nate Aronson found mother and child locked in the car, not knowing the if they were injured. Officers broke a rear window to gain access and assess both.

MacRoberts was suffering from an apparent drug overdose and was treated at the scene. Police said an investigation confirmed MacRoberts used heroin prior to the crash.

Other than the overdose, MacRoberts was not injured. Her child was also unharmed. Police noted the child was in a car seat at the time of the crash, but the seat was not properly secured.

MacRoberts was then taken to Tobey Hospital for treatment while her child was taken to the Wareham Police Department to await the arrival of family members.

MacRoberts was not arrested at the scene because she required medical treatment for the overdose. She has been summoned to Wareham District Court to face the following criminal charges: operating under the influence of drugs, first offense; operating after suspension; operating to endanger; child endangerment while operating under the influence; marked lanes violation; failure to properly restrain a child under 5.

Police Chief Kevin Walsh explained that police use the summons process for cases when suspects require medical treatment following an incident. He said MacRoberts remained in the hospital on Sunday.

“The normal course of police action is to file the appropriate charges against the person, using the court summons process,” said Walsh. “This process is used when the patient has been charged with the offenses as if the physical arrest was made, but cannot obviously occur because the person is incapacitated.”

Wareham Police noted that because MacRoberts was not arrested, a booking photograph is unavailable.
