Nicolas felt neglected and ignored by his father after Myriam came into their lives. Guy Ullens, his father, gave his four children €50,000 per month, but Nicolas was not satisfied with that. On the day of the murder, Nicolas stormed into his father’s office in Lasne and demanded an explanation about the sale of the magnificent villa of Ohain.
