The Moonlight Sonata Killer

New York City, a densely populated metropolis, was where Ten resided. His father was the most known serial killer in the city. He was notorious as the Moonlight Sonata Killer. In the light of the moon, he strikes. By the crack of dawn, he’s gone. Another very important person abided in the magnificent city of New York, and her name was Cin. Both of her parents were detectives who investigated in the Sonata Case. Sadly, they did not solve it, nor live to see the day that he’s been caught.
This year was Cin’s first year in college, studying criminal justice. The topic was on the Moonlight Sonata case which a significant amount of people were curious about. The curiosity was because of the lack of information on the unknown cause of death of all

“We would get into that in a bit, but to simply explain, they had to be very tall be to be able to reach the height where the corpses were placed.”
Professor Kon headed towards the phone as it was ringing, and he looked frustrated. “I apologize, class will have to end sooner today. Any last questions?”
“Sir, is it true that the killer has a son? Everyone was just wondering… since, there was a student who looks like him…”
“I will confirm this, since there is too much unnecessary attention and curiosity of that topic, but I do believe that the killer does have a son… I cannot reveal if he attends here or not.”
After the class ended, Cin went to her dorm room and took a nap. By the time she woke up, it was around 11pm.
“AAAAAAAAAHHHHHHHHH!!!!!!!!!!!!!!!!,” screamed a girl.
Cin ran out out as soon as she heard the scream, and she could see all of the other girls outside of their dorms too. Every girl ran to the common area of the dorms.
“What’s wrong?!,” said Cin. The girl was on the floor leaning back and moving back pointing into one of the rooms. Cin ran immediately into the room, and saw a girl whose death was exactly the way the Moonlight Sonata killer had murdered all his victims. She broke down emotionally and fell to the

Cin! Are you okay?,” said one of the girls. Cin started to lose her vision and fainted. About 5 minutes later, Cin woke up in the scene, and stood up to walk outside. The police has arrested one of the guys over at the dormatories.
“Who did the detectives arrest?” said Cin.
“Umm, I heard it was the number one suspect… Ten Kim. Supposedly, he’s the guy’s son…” said Lisa, Cin’s roommate.
Cin thought to herself…
“So it was true, the killer’s son was here.”
Meanwhile, at the police department…
“According to the files, she was killed around 10:09 pm. Where were you at 10:09 pm?” said the detective.
“I was in my dorm, the entire night. You can ask my roommate… I never left the dorm.” said Ten staring at the wall.
“Go check with the roommate.” said the detective. “Are you familiar with the Sonata Case?”
“Yes, I am familiar with it…” said Ten.
“The victim was murdered the exact the same way your father, the Moonlight Sonata killer murdered all his victims. Are you aware of that?”
“No, I am not aware with whatever you’re assuming. If you don’t have any proof or evidence. I would like to leave,” said Ten.”
The detective seemed frustrated and not knowing what to do next, he let Ten
