BOSTON (AP) -- The state Appeals Court has upheld the conviction of a Boston woman with ties to Lowell who was convicted of a setting the fire that killed two sisters ages 14 and 3 in 2008.

Nicole Chuminski, 31, was convicted of two counts of second-degree murder in 2010 for the deaths of two daughters of Anna Reisopoulos.

Chuminski appealed the conviction saying prosecutors hadn't proven the fire was started with acetone. But the court said prosecutors had strong evidence of Chuminski's guilt and did not have to establish that an accelerant had been used.

The bodies of 14-year-old Acia and 3-year-old Sophia were found in an embrace in the attic.

Reisopoulos escaped but spent more than a week in a hospital recovering from injuries.

Prosecutors say Chuminski set the fire at Reisopoulos' South Boston home in April 2008 after the two argued at a wedding they attended.

Chuninski was arrested on May 9, 2008 at 242 Ludlum St., in Lowell, where officials said she was visiting her sister. Chuminski had initially been reported to be from Lowell, but officials said there was no evidence she lived with her sister.
