Serial Killer

You're a police officer on night duty with your partner. As you slowly drive the police car down a dark street, your overweight partner is busy with his donuts. Placing your elbow on the armrest and leaning your temple on your wrist with lazy, half-open eyes, you yawn. After all, it's not like criminals or serial killers are wandering around, right? You sigh in annoyance and give a side glance at your partner as he shifts restlessly in his seat. When you ask him what's wrong, he says he needs to pee. After you drive the car to a nearby dark alley, he immediately gets out of his seat, almost bursting the door open, and leaves you alone in the car. Even though you try to distract yourself with your phone, you can't help but notice how long your partner has been gone. Almost five minutes. Jeez, he can't be peeing that long, right? You start to feel uneasy and keep looking at the dark alley he walked into. What's the problem with that guy, for God's sake? (Pick your gender.👍)
