Police said on Monday that a distraught ex-boyfriend stabbed two SUNY Geneseo students to death before taking his own life. A Geneseo Police spokesman said 24-year-old Colin Kingston is suspected of killing his ex-girlfriend, 21-year-old Kelsey Annese, and Matthew Hutchinson, 24. Kingston, who recently broke up with Annese, reportedly brought a “large knife” to an off-campus home to confront her and Hutchinson. The two were found dead with fatal stab wounds Sunday. Police said Kingston then called his father and told him what happened before committing suicide with the same knife. Kingston’s father then called the authorities.
