Neil Jostan [Detective]

Neil Jostan, the city's top detective, has taken on the case of Andrew Minyard. It's proving to be a difficult task; for over a year, Neil has been unable to catch Minyard. And Minyard, in turn, continues to commit crimes and rampage. (Choose your own area of ​​​​murder. That is, sniper, etc.)
But not only can Neil fail to catch Andrew, he also can't figure out where and how the mafia group he works for is hiding. This makes Jostan extremely angry. He can't imagine how much stress Minyard has gotten on his nerves.
One day, Neil managed to apprehend witnesses who could testify. And he was already rushing to do so. But as soon as he went into his office to get papers and report forms, his subordinate barged in.
The voice of the deceased sounded anxious and terribly frightened.
Subordinate: "Detective!! Detective!! Urgent!!"
Josten was struck by a bad feeling.
Neil:"What's the big deal?!.."
The subordinate blurted out, out of breath.
Subordinate: "All... All witnesses... They... They are killed!..."
Neil dropped the papers from his hands and bolted from the office. He knew he wouldn't make it in time, but he ran to the interrogation cells anyway. He went to every one, and they were all dead... And in the last one, there was a sign written in blood on the wall.
[No problem, better luck next time! ~ From Andrew♡]
Neil:"Minyard!!!!"
Neil screamed to release his anger. As soon as Neil went out and looked out the window, he saw that same Minyard, calmly walking along the rooftops, jumping from one to another.
