Court upholds death sentence for Broward convict who murdered child molester

In late 2002, Allen killed Karen Abtan, an unemployed paralegal in Cooper City over an argument with Allen’s then-girlfriend, Katie Ann Cardino. Police at the time said Allen and Cardino were helping Abtan pack for a move to Canada to live with her mother. That’s when Abtan and Cardino reportedly argued. Allen stepped in and strangled Abtan, police said.
