The Maine Attorney General’s Office is looking for an increase in the budget for the state Medical Examiner’s Office, driven mainly by a sharp spike in drug overdose deaths. Attorney General Janet Mills, whose office oversees the medical examiner’s office, said drug-related deaths are more expensive for the medical examiner to handle, usually because the toxicology reports used to determine what drug caused a death are much more complex and time-consuming. Her office is seeking a budget increase of $230,000 for the medical examiner’s office. The request comes as the number of drug-related deaths in Maine in 2016 hit a record high of 378, up from 272 in 2015.
