The Bristol County District Attorney's Office says Fall River Police were arresting a Dartmouth woman on outstanding warrants when Scott Macomber interfered.

DA Spokesman Gregg Miliote says on Monday afternoon, police had followed 37-year-old Lisa McNally into a home on Mount Hope Avenue to arrest her on outstanding warrants out of New Bedford and Fall River District Courts.

As they attempted to arrest McNally, the 48-year-old Macomber intervened and was tazed by police before being arrested and placed in the back of a cruiser.

Miliote says police followed protocol and called Fall River Rescue to attend to Macomber after the tasing. While they were en route, Macomber went into medical distress and was rushed to St. Anne's Hospital where he was pronounced dead.

The DA's office continues to investigate the death and an autopsy is being performed.

Meanwhile, McNally was arrested and has been arraigned in New Bedford District Court on the warrant charging her with threats to commit a crime and was released on personal recognizance. McNally faces arraignment in Fall River District Court Wednesday morning for the probation warrant related to a past shoplifting-third offense incident.
