The man suspected of mugging six women and threatening them with an ice pick in the Bronx and Manhattan was arraigned yesterday, and his cousin offered an explanation about John Martinez's alleged actions. Kenny Colon said Martinez was "stressing about how to afford everything for the holidays... He was thinking about beinggood to his family and Christmas ... not about hurting anybody." Well, in one instance, he was upset that one victim didn't give him enough money, "This is not enough. Take me to your apartment or I will stab your son." No one was hurt in any of the muggings.
