Why/How:

Detectives assigned to the Robbery/Homicide Unit have arrested a woman for the murder of her husband following a domestic related dispute in unincorporated Seminole.  

At about 3:23 a.m. on Monday, July 10, 2017, deputies responded to a 911 call from a female caller located at 9500 Hamlin Boulevard #1206, in unincorporated Seminole. Detectives say the caller, identified as 52-year-old Mary Pender-Michielson, reported that her husband 41-year-old Bruce Michielson sustained a knife wound to his chest during a domestic related argument.

Bruce Michielson was transported to a Bayfront Hospital and was pronounced deceased at 4:40 a.m. on Monday, July 10, 2017.

Mary Pender-Michielson was transported via ambulance to a local hospital for a non-trauma related medical complaint.

When detectives interviewed Mary Georgia Pender-Michielson, she admitted to stabbing her husband Bruce Michielson in the chest with a large kitchen knife during the domestic dispute. Detectives say Mary Georgia Pender-Michielson gave investigators multiple inconsistent statements as to her account of what took place.

Mary Georgia Pender-Michielson claimed the stabbing was in self-defense; however, detectives concluded the evidence did not support the justifiable use of deadly force towards her husband. 

At the time of the stabbing, Mary Georgia Pender-Michielson and her husband Bruce Michielson were the only two persons at their private residence.

Witnesses also confirmed there was a history of domestic violence between Mary Georgia Pender-Michielson and Bruce Michielson.

Mary Georgia Pender-Michielson was arrested on Thursday, July 13, 2017, at West Bay Largo Medical Center and was transported to the Pinellas County Jail without incident. She was charged with murder in the second degree.

The investigation continues.
