BROOKLYN - A man accused of killing four people and wounding four others during a 28-hour rampage in February pleaded not guilty to murder charges in a Brooklyn court today.

Maksim Gelman has already pleaded not guilty to assault and attempted murder in Manhattan, where he was tackled and arrested by police on a subway train near Times Square.

Authorities say Gelman unglued after his stepfather wouldn't let him borrow his mother's car. He's accused of stabbing him to death before making off with the car and going to the home of an acquaintance, killing her and her mother.

Gelman is also accused of running down a pedestrian, carjacking and other violence.
