Suspicious Fires Popping Up In Roslindale: Three overnight fires in Roslindale Square. With some raw footage of pickup in flames on Poplar Street (by Adams Park?).

To get to the other side of town before police realized he'd set an Audi on fire.

Nicole Chuminski, 25, has been arrested and charged with setting the fire that killed Acia Johnson, 14, and her sister Sophia, 2, on April 6.

She will be arraigned on two counts of murder in South Boston District Court on Monday, according to the Suffolk County District Attorney's office.

At a press conference today, Suffolk County DA Dan Conley said that during their investigation of the fatal fire, police quickly learned that:

Chuminski and the victim's mother had an argument in the hours preceding the fire. They obtained evidence that Chuminski was present near the scene around the time of the fire. And they determined that an accelerant found on Chuminski's clothes after the fire was consistent with an accelerant discovered on the door frame of 154 West Sixth St. These facts - as well as others we cannot divulge today - support the complaints obtained this afternoon in South Boston District Court.

The girls' mother, Anna Reisopoulos, and Chuminski allegedly had a tempestuous relationship. Reisopoulos was charged with assault and battery on Feb. 1 in connection with a physical altercation at the now destroyed house.

The Crimson reports on flaming manholes early this morning:

A fire started underground on the corner of Mass Ave and Dunster Street was visible through several manholes in the Square this morning. Harvard's Holyoke Center, Cambridge Savings Bank, Au Bon Pain, and other nearby institutions were evacuated, and automobile access to the Square had been severely restricted by the Cambridge Fire Department. ...

Of course officials think a brush fire in Revere was set on purpose.

Four-alarm brush fire in Stony Brook Reservation (that might explain why it smelled like wood smoke when we drove through the reservation and Dedham Center around 2).

Why it went to four alarms.

Dave Daniels happened upon firefighters putting out a bus fire by Emmanuel College yesterday.

It's the same bus Evan watched melt and explode.

Evan was there with a camera:

... It was pretty spectacular...at first, I saw the driver behind the bus waving his arms and cursing. There was molten stuff dripping beneath the back of the bus that was flaming...then the flames started to grow and reach for the trees above the bus. When I heard a small explosion and the back of the bus blow off, I decided to walk away and watch the rest of the action from the safety of our lab building's front porch. ...
