"I came outside and I heard a helicopter and then I saw the son-in-law drive off," a neighbor told Local 10 News.

After the shooting, Kasimow, 52, fled in his black Mercedes-Benz, driving several miles north to Hollywood.

When Hollywood police caught up to the car, officers found Kasimow dead from a self-inflicted gunshot wound.

Linda Marx, a well-known real estate agent in South Florida, was shot to death by her son-in-law.

Thomas said a preliminary investigation revealed that Kasimow and his mother-in-law "were dealing with ongoing family issues."
