Note: Some outlets are reporting the student was a girl, the family says it was a boy.

A Florida man shot and killed his ex-girlfriend on Tuesday in front of six children, including the victim’s 10-year-old son, who was taking his online Zoom class on the first day of school.

Donald Williams, 27, went into the home of 32-year-old Maribel Rosado-Morales and confronted her about something to do with a video. 

The two began to argue and when Maribel smiled at Donald he shot her in the chest twice.

The entire incident took place while Maribel’s son, Brian, was in the middle of an online Zoom class.

Sheriff William Snyder told reporters at a news conference:

The teacher said that she heard a commotion, heard profanity, and realized there was some kind of domestic altercation. The teacher said she mutes her button so nobody had to hear it, and then she sees the 10-year-old put his hands up to her ears.

Moments later a bullet hit the child’s computer and the screen went blank. The little boy was not hurt. 

Maribel’s other son tried to stab Donald Williams with a kitchen knife, but he turned the gun on the boy and he dropped the knife and raised his hands.

Williams fled on a bike and went to a nearby laundromat. Then, he hopped on a commuter bus. His strange behavior prompted the driver to exit the bus and call 911. 

Police arrested Williams a short time later. 

He is facing charges of premeditated murder, two counts of aggravated assault, one count of burglary, and one count of being a convicted felon in possession of a firearm.

Donald Williams is being held without bond.

Following the shooting, Maribel was rushed to Lawnwood Regional Medical Center and Heart Institute. 

Her brother, Jose Crespo, said she was awake and talking to fire rescue officials about how her sides were hurting.

“She was talking and we thought she would be fine,” he said. “Maybe something went wrong in surgery; I don’t know.”

Maribel died later that day.

Martin County school officials said the teacher and students who heard the commotion are meeting with counselors.

My prayers are with the family of Maribel Rosado-Morales and the children who witnessed her murder.
