An Orland Park man is pleading guilty to the deaths of a pregnant woman and her three children as a result of a crash in Beecher. Sean Woulfe entered his plea today to five counts of reckless homicide. The deadly collision happened in July of 2017. Prosecutors say Woulfe was driving 84 miles per hour seconds before he crashed into Lindsey Schmidt’s vehicle, killing Schmidt and her three children. In 2018, the father and husband of the victims settled a civil lawsuit against the defendant for 300 thousand dollars.
