The GX-3 Incident

The GX-3 Incident is an unsolved mass murder thought to only be possible by a superhuman, though the culprit is unknown to this day.

Specifics of the Crime
Location: Blackport, duh. Specifically a rooftop of one of the big skyscrapers. It doesn't really matter which one, probably.

Victims: 9 people:

-A man in his 70s

-A woman in her 60s

-A man in his 30s

-A woman in her 30s

-A teenaged girl

-2 teenaged boys

-A man in his 50s

-A woman in her 20s

It was hard to identify them at first due to the extreme facial distortion of the corpses. This was before forensics was really a thing. The identities of the victims were supposedly known by the police but never released to the public.

The bodies were all heavily mutilated with any identifiable features fucked up to the extreme. It's hard to imagine a regular person being capable of this. The only possibilities are a superhuman culprit or a group of culprits. However, even with a group, it's hard to imagine what would be capable of causing such injuries. A message in their blood was written next to their bodies. Well, I say message. It was only a single word.

"Ha."

Suspects
A number of possible culprits have been suggested by investigators:

-An Unknown Supervillain: Regarded as the most likely solution, simply because the known supervillains probably would have revealed that they did it.

-Zookeeper: Some say that animals could have been that mysterious weapon. Elephants are pretty strong, after all.

-Jiggledoom: Her brutal powers fit the brutality of the murder, and the "Ha." is something she'd say. Only problem: she was seen on the other side of the world the day before the bodies were discovered.

-Dick Dapper: Okay, this one seems crazy at first. But what if Dick Dapper was experimenting with some new technology? That would explain why the police never released the identities of the bodies to the public. Perhaps there's something incrimiating there?? Also, Dick Dapper was seen in Blackport around the time of the crime.
