Looking for a TV movie title

Hi, I´m looking for a movie where parents first killed their young child (maybe baby) to get insurance money. They have a son in his 20´s and he finds a girlfriend that he and his parents can also kill for the life insurance money. They almost kill her when they went hiking. They try to kill her mulitiple times. I don´t remember if they succeeded in killing her but the parents and the son were convicted of attempted murder or murder in the end. It was a movie on TV and the actor that played the son is blonde and a well known actor from the 80´s and 90´s. I don´t know his name though.

Justice for Annie? I haven’t seen this movie in years but I recall the girlfriend being pushed off a cliff and they may have tried to kill her before for insurance money. The true story says a 3 year old child was killed by hanging and insurance was collected. Ex husband was also killed and the killer collected even more insurance.
