A Schenectady woman has been convicted of stabbing her neighbor to death. Last December, Tina Karuzas, 28, was having a little party in her second-floor apartment. Downstairs neighbor Latoya Ebron, 26, got sick of the noise and came up to demand that Karuzas turn down the music. When Karuzas didn’t comply, Ebron returned and the two women started arguing. Police say Karuzas stabbed Ebron once in the stomach, killing her.
