Trying to get cartel influence to zero in Westville

So I've had all of westville unlocked for a while now, tagged all the grafitti spots, got all the customers, but there's that nagging 50 influence left that won't go away. Reading online tells me that's because there's a cartel dealer who lives next to the tattoo shop who needs to be killed. But because I've already got everyone unlocked, he only pokes his head outside at midnight for like 0.01 seconds. I've tried waiting there to shoot him at that moment but he's just TOO GODDAMN QUICK. My reflexes are just not up to the task. By the time my eye registers he's there and my finger clicks the mouse, he's gone again. (disclaimer, I'm over 50 years old and have shitty eyesight and reflexes, okay?) So how do I fix this? Is there a console command to FORCE him outside? Is there some other way to address this? Please don't just tell me 'skill issue' or something. Give me actual options.
