Maffei was particularly agitated on the day of the shooting because Ranta, had recently moved out of their Parkland home and into the Barrington Club apartments. Ranta said she was taking special precautions to hide from Maffei and did not let him see their son for about 2 ½ weeks because she was waiting for a formal court-ordered custody-sharing agreement, according to court records. Her car tire was slashed outside the house about an hour before the shooting, police said.
