Michigan State Police trooper guilty of assaulting partner

A Michigan State Police trooper charged with assaulting a female colleague was found guilty Thursday on four charges, Attorney General Dana Nessel announced Friday.

Adam Mullin, 25, of Millington was charged in February and an investigation was launched. 

The charges include one count of obstruction of justice, a felony punishable by up to five years in prison and/or a $10,000 fine; one count of obstructing a police officer causing injury, a felony punishable by up to four years in prison and/or a $5,000 fine; one count of aggravated domestic violence, a misdemeanor punishable by a year in jail and/or a $1,000 fine; and one count of assault and battery, a misdemeanor punishable by up to 93 days in jail and/or a $500 fine. 

A felony charge of misconduct in office didn't go to the jury for consideration. 

Nessel said Mullin's law enforcement certification was revoked and he was fired. 

"Domestic violence is a serious matter and we are steadfast in holding those who commit these acts accountable — law enforcement and civilians alike," Nessel said in a statement. "It is serendipitous that this verdict comes during National Domestic Violence Awareness Month and it reminds us of the work that still remains to end this epidemic in our state and nation."

Mullin will be sentenced Dec. 2 before Huron County Circuit Court Judge Gerald M. Prill. 

In 2018, Michigan State Police's Incident Crime Report showed 48,264 reported instances of domestic violence.
