I would've thought of a creative title for this case, but damn my penchant for the dramatics.
Forgive me in advance for rambling and being unable to go exactly straight to the point: got to give you everything I know about this creep endangering the kids.
The Case
One of my brothers happened upon this while making a detour in Lawrence, and knew in an instant that he's got to stay: children falling prey to an unknown illness. This apparently began two weeks ago, the first victim being an eight year-old boy living in **** Vermont St. Doctors are baffled by the cause, and the illness' effects strongly resemble that of a person experiencing the effects of blood loss. One child has already succumbed to death due to severe anemia.
Victims have been chosen at random - the oldest being 10 years old and the youngest, six. Upon further investigation, Q (let's call my brother this for now) found out strange markings persisting in each child's room - the window pane, in particular.

Clumsy, rigid scratches made by stiff fingers in an attempt to write something in an dying regional alphabet in my country, children falling ill and one dying because of severe anemia... Now here's what's putting those kids in danger.
The Perp
You'll be hunting for a creature called binangunan. It's a bloodsucker in Kapampangan lore (from the province of Pangasinan in the Philippines) that targets children as its main food source. Sounds like a vamp, right? This one's different, though, because unlike your regular vampire, this freak of nature can suck a child's blood even without having physical contact with the victim. This blood sucker doesn’t kill its victim at once but feeds off him/her for days or weeks until the victim finally succumbs to a severe condition. With the victim in near death, the blood sucker moves on to another child to feed on. But our perp right here is quite greedy to be preying on multiple kids (or trying to be smart enough to cover up its identity and MO), then done the unthinkable and actually drank too much to the point that one of its victims died. Nasty son of a bitch. Lucky one of my relatives actually found out the trick to their weird bloodsucking. But I'll save the hows for later (or whoever's curious), because what you need to know is how to identify and kill it.
What to keep in mind when identifying a binangunan in disguise: this creep looks entirely human, except for bloodshot eyes, pale skin, and a perpetual blank look on its face. What sets it apart from a vampire is that it can roam around during daylight without being harmed, so there's that. Q (poor guy's asthmatic; not built for the hunting life so he can't take this case) wasn't able to pinpoint an exact suspect, but he's investigated enough to know that who you're about to look for is a woman in her mid-thirties, most probably Asian, and is highly likely recently employed in a job where she's usually seen with children: could be in a school or a hospital, those two are our best bet.
A binangunan despises an adult's blood so much to the point that it displays extreme discomfort whenever in the presence of an injured grown-up, so I suggest you nick yourself somewhere that won't impede you - as long as you can keep the wound exposed. This is the second step in identifying a binangunan in disguise. It hangs around areas where kids frolic everyday, so your best bet for further identifying your mark is to hang out near parks or schools. Or the kiddie section in a hospital.
Now, the actual How-to in slaying this ****er
While bearing differences from a vampire, a binangunan can be killed like the former through beheading. Here's the twist, though: you'll need to coat your machete (or sword, or whatever beheading tool of doom you're using) with - you got it right - an adult's blood. Not dead man's blood. An actual, living adult. Like I said, these creeps hate a grown-up's blood with a passion - it's like they're allergic or something but what's more, they actually experience allergic reactions ranging from mild to severe depending on the amount of adult blood they come in close contact with. So if you're feeling bold enough, splash some blood on our perp's face. Only if you want to.
If you can't part with a single drop of your blood, you can look for Q in Lawrence. He'll be more than willing to do an impromptu bloodletting for this hunt. His address is **** Vermont St.
If you have further questions with regards to our little ray of sunshine monster, shoot me a message. Q doesn't know much about Kapampangan lore, so he'll only be useful at scouting and providing his blood for killing the binangunan.
I hate how this title's topic make me sound like a demanding a-hole, but please forgive me. I may not be fond of kids, but I can't stand seeing them being preyed upon. Just, please. Kill the binangunan. Save those kids. I'll be forever (as long as I'm alive, I mean) in your debt or something if you take and clear this case.
Thank you very much.
Ah, might as well tell you how a binangunan can suck its victim's blood without making physical contact with the latter. Something you can share with other hunters should they come across this particular freak. Add this in your libraries. 👌
