The Times Herald-Record of Middletown Reports Jean Pierre has filed a notice of claim alleging the city of Newburgh permitted a dangerous condition at its waterfront boat ramp that allowed LaShanda Armstrong to drive her van into the river on the night of April 12.
Armstrong and three of her four children drowned. Her 10-year-old son escaped through a window and swam to safety.
Pierre, Armstrong's estranged boyfriend, claims Orange County's Department of Child Protective Services had the responsibility to monitor the 25-year-old woman.
County officials haven't commented on the pending lawsuit.
