Certainly! Alexis's storyline can go two ways from there. For both of them, she needs to have at least 60 LP, so best check that.
Path number 1: Convince her to go to the police with her story. For that, you need to meet Alexis between 8:00 and 20:00 and it shouldn't be a date (at the gym, for example). After you did that, invite her on a date at home.
Path number 2: Hire a PI. To do that, you need to go into your phone, go to the service icon (second lane, rightmost icon). There should now be an icon which lets you hire a Private Investigator. Once you've done that, you need to wait a bit until he calls. Then, after that, he will call you again and give the location and you can go confront scumbag (you need either a car or a bike for that to happen. Also, you can buy a baseball bat if you want, but I don't think that changes the outcome, only the scene itself). Once that's done, meet Alexis at the pub (can be a date). Note that this path results in her KP being raised to 100, which is the only way to collar her if you want, so personally, I kinda recommend this path.
Please note that these two paths are exclusive, so you can't do both. Once you've gone to the police, you won't be able to hire the PI, and similarly, once you've hired the PI, you won't be able to go to the police.
As always, for more information, please consult the wiki.
Huh, I just got an idea. Since Path 1 doesn't do much, could it be changed in a way that would allow the MC to meet Camila there, as well? It might be beneficial, since the way she's currently met through the whole Kylie-storyline is a bit much of a chore and also doesn't always work properly... Is that a good idea, folks?
