Antonio Marcos Ferreira, 38, was arrested today in
Charlestown and charged with first degree murder. He will be arraigned
on Tuesday morning in Malden District Court.

According to
authorities, on Friday, October 2, Everett Police responded to a 911
call which had been made at 4:32 AM reporting a woman with multiple
stab wounds. Police went to 154 Main Street in response to the call and
discovered the victim, later identified as Sheila Dos Santos. She was
pronounced dead at the scene.

The victim was transported to the
Office of the Chief Medical Examiner and an autopsy was performed. The
ME ruled the victim's death a homicide caused by multiple stab wounds.

Everett
Police and Massachusetts State Police assigned to the Middlesex
District Attorney's Office commenced an investigation into the
circumstances of the stabbing.

Based on that investigation, it
is alleged that the defendant stabbed the victim outside her apartment
multiple times earlier in the morning. The defendant and victim dated
off and on until nine months ago when the victim told him she no longer
wanted to date him. The defendant continued to pursue a dating
relationship with the victim, despite her rejection. It is alleged that
the defendant expressed extreme displeasure with her rejection of him,
ultimately stabbing and killing her when she returned home from work
early that morning.

Evidence has placed the defendant in the
vicinity of the murder at the time that it is alleged to have occurred.
DNA evidence has also further connected the defendant with the murder.

These charges are allegations and the defendant is presumed innocent until proven guilty.
