Mark Edward Anderson

Detention Deputy Mark Anderson suffered a fatal heart attack after interacting with a belligerent inmate in the Olmsted County Adult Detention Center.

Deputy Anderson was working alone managing gym-use time for inmates when one of the inmates became extremely upset, prompting Deputy Anderson to call for emergency response from other deputies. Additional deputies responded and they escorted the inmate back to his unit.

Deputy Anderson was preparing for a subsequent shift when he collapsed in the locker room.

Deputy Anderson had served with the Olmsted County Sheriff's Office for 11 years. He is survived by his daughter and brother, as well as his significant other and her son.

The true measure of a person
is not found in the
might of their arm,
their wealth
or their power –
it is found in the strength
of their character.

There is no greater testimony to
ones character, than ones
willingness to sacrifice all,
in the noble quest of
providing protection to all
whom they serve.
