Schenectady police have arrested a teen in connection with Tuesday morning's stabbing on Germania Avenue.
Bridgette Fiorentino, 19, is accused of stabbing her ex-boyfriend Alvin Williams in the back while in front of their 20-month-old child. Police say the stabbing happened after Fiorentino mistakenly thought Williams was with another woman.
Fiorentino is facing charges of felony assault and endangering the welfare of a child as well as a violation for possession of marijuana.
