According to KKTV, 31-year-old Jacqueline Souza was arrested on suspicion of murder after allegedly getting into an argument with her fiancé, Brandon Watkins, 33, stabbing him with a steak knife at the Colorado Springs home they shared.
Investigators say Souza gave them several different accounts of what led to her fiancé's death at first.
Initially, Souza told police that she and Watkins were returning home from a bar celebrating their upcoming wedding in Las Vegas when they began to fight over his desire to invite an ex-girlfriend to their wedding.
According to arrest papers, Souza called 911 around 12:30 a.m. early Saturday morning to report that her fiancé was bleeding and had dropped to the floor in their kitchen.
