Although Murtaugh thinks that Butters is gay, it is revealed that Butters has secretly been married to Murtaugh's daughter, and only Riggs and his wife know this.
Lethal Weapon 4
Lee Butters is first shown after Team Riggs/Murtaugh foil a raid on a ship carrying Chinese slaves. He is happy to see them both and even shows his gratitude by telling someone to give Roger Murtaugh a towel (even though he didn't need it). Butters inspects a dead Chinese body and becomes so enraged, he thinks people are crazy for killing an innocent being and bringing dead bodies to America. Then reporters start looming in and Butters shouts at them to leave the premises.
Butters is then shown in the police station talking to Murtaugh.
- Lee Butters may have inspired the character of James Carter (played by Chris Tucker) from Rush Hour, which was released the same year as Lethal Weapon 4.
