Wayne Davis (Gary Cole) is a police officer, Katherine's first husband, and the father of the "real" Dylan. It is shown in flashbacks that he beat his wife and also had a drinking problem, causing Katherine to leave him. He spent twelve years trying to track Katherine and his daughter down and discovered Katherine is back on Wisteria Lane. He wanted a relationship with his daughter, or who he thought to be his daughter, until Katherine informed him that Dylan is not his child. Upon hearing this, he has a DNA test done at the forensics lab. The test results come back concluding that he is not Dylan's father. He tries everything in his power to find out what actually happened to his daughter, even threatening to kill Katherine so she would tell him. He then held Katherine hostage along with Bree, until Katherine finally told him what really happened with Dylan (see Dylan's section). When Wayne finds this out from Katherine, he attempts to kill her, until Adam comes and a fight between the two ensues, resulting in Adam overpowering Wayne. While laying on he floor, Wayne threatens Katherine, telling her he may go to jail, but his friends at the police will help him get out and that he will come after her again. After realizing the truth in his statements, Katherine shoots him in the chest, killing him instantly.
