Hundreds of police are searching for Sang Ho Kim, a man described as a disgruntled business associate who reportedly walked into an office near the Roosevelt Field mall in East Garden City, New York, on Wednesday morning and opened fire. Two people were shot at, and one was killed. The attack was said to be targeted to a specific person in the office "over a bad business deal," according to Nassau County police. Nearby schools and businesses were put on lockdown. Authorities are now saying that the search includes the tri-state area.
