Being a Good Detective

1
Have excellent communication skills. Interpersonal communication skills are one of the most important tools for a successful homicide detective. Much of your job is spent talking to people, whether it be the families of a victim, a murder suspect, or other law enforcement officers. Effective communication combines many skills including the ability to completely listen to details, asserting yourself, and recognizing the emotions of the person you're talking to. To become a better communicator, pay closer attention to what the person is saying both verbally and non-verbally, and stay in control of your emotions. In addition, be concise and complete with directions you give, and become better at being insightful to other people's feelings and emotions.^{[15]
