A South Jersey mother has been arrested after her 2-year-old daughter was found unresponsive in her car seat, while she was in the front seat allegedly getting high.

NJ.com reports, Deana Joseph called police to her home in Alloway Township, after she found her daughter unresponsive in the back seat. Currently, authorities aren't sure what caused her death and are awaiting for the autopsy report from the regional medical office.

To make matters worse, this isn't Joseph's first offense in child endangerment or drug possession. According to NJ.com, she lost custody of two of her children following two incidents where she was high while her children were left unattended. In addition, she also has a 20 year history of drug possession and use.

NJ.com says it is unclear whether or not she was being monitored by the state's child welfare services. If convicted of second-degree child endangerment, she could be facing up to 10 years in prison.

This is such a heartbreaking story, and could have completely avoided. Our hearts go out to that little girl's family.
