Prosecutors say a man charged with a violent home invasion in Cambridge has been linked by DNA to the rape of two college students in Boston.
Marcos Colono was arraigned on Tuesday in Suffolk Superior Court on aggravated rape and other charges. The 23-year-old was held on $1 million bail.
A prosecutor said Colono, armed with a knife, forced his way into the victims' apartment in September 2008 and raped the women repeatedly.
During the Cambridge incident in August, Middlesex prosecutors allege Colono sexually assaulted an 11-year-old boy and stabbed the boy's father. He's pleaded not guilty in that case.
Authorities say Colono's DNA was matched to evidence from the Boston crime scene. The Suffolk District Attorney calls Colono a "suspected serial rapist."
A message was left with Colono's attorney.
