The state's highest court has upheld the first-degree murder convictions of a man in the 2004 slayings of a mother and her 12-year-old daughter in Woburn.
Michael Bizanowicz, a Level 3 sex offender, killed Joanne Presti and her daughter Alyssa.
He had appealed his conviction, arguing, among other things, that police should have looked at another suspect.
But the Supreme Judicial Court ruled against him today.
"We reject the defendant's claims, affirm his convictions of murder in the first degree, and, after review of the entire record ... decline to exercise our power to grant extraordinary relief," the court said in an opinion written by Justice Judith Cowin. Cowin wrote the opinion before her retirement last week.
