Serial Explosions, the third house. (Open)

M then whistled to the mother that was sitting at bench near Shun and the detectives. The mother came slowly towards M and then M explained a plan to her. He then turned to some policemen and asked them calmly: "See if you can get people that can act as reporters."

Meanwhile Shun was talking with Jimmy: "What do you want to know?"

Jimmy continued the conversation with Shun as M set up a plan.
"First, where did they meet? What did you like doing together?" He started off with some basic questions.

"We met slowly..." Shun said smiling a bit while remembering the good old times. "First it was me and Orito. We met at kindergarten..." Shun placed palm on head, "forgot exactly how, but we met there." Shun took the palm off head continuing to speak. "Later in school we met Akemi. I didn't really mind her much... until grade 6, where we became friends." Shun said raising his head up. "And finally when i was 14... Minori moved in this neighborhood and after our parents became good friends, i met him." Shun finished his story and now was ready to answer the second question. "We usually play games together on gaming consoles... play basketball at school's playground or take a walk around city, neighborhood eating snacks."

This confused Jimmy slightly.
Were they the ordinary group of friends they came across as, at 16 years old and already having people try to blow them up? That just didn't make sense, there had to be some contradiction, some giveaway somewhere...!
"When you have eliminated the impossible, whatever remains, however improbable, must be the truth..." He thought to himself slowly.

"Wait..." Shun suddenly wide opened his eyes. "It... it can't be true... can it?" Shun look down grabbing his head with both hands. Shun was trembling horribly from thoughts in his head.

"Huh, what can't be true?" Jimmy asked.

"The man... the theft... the murderer!" Shun said while still holding his head with both palms trembling.
He could remember the face and his crime... his last words before he was arrested. But not the name... no... the name was totally erased from his mind.

"Huh?" Jimmy looked at Shun, bemused about what he was talking about. Was he trying to recollect some past memory?
Jimmy stepped forward, putting his arms on his shoulders.
"Look, whatever you can tell us would be of great importance to us..." He spoke soothingly and slowly, trying to console the victim.

"A theft... no... a murderer..." Shun slowly took hands off head. "Me and my group caught years two... no wait.. less than two years back... a man that murdered a woman for money." Shun said and strengthened his fist. "We saw him bring out the corpse from home and then left with bag of money. After following him, me and my group called the police and he got arrested for money stealing... but there wasn't proof to arrest him for murder."

Jimmy looked genuinely concerned.
"Did he know what you looked like, your names or any information about you?" He asked. "In fact, do you know what he looked like or what his name was?"

"He saw my face... but about the name... i'm not sure." Shun said looking down on his feet. "I know only his face... but the name... no... that is erased from my mind."

"Quick, tell me what he looks like." Spoke Jimmy, taking a step back from the boy and whipping out a notepad ready to write down important information or do a sketch.

"Well.... he is..." Shun reached his hand up that was high above himself, "he had.. um... thin facial hair and short brown hair..." Shun wasn't really sure about what he was talking about. "He didn't seem old... like 25-35 age and he is thin..." Shun looked down on his feet again and then looked back to Jimmy: "I haven't seem him more than a year, it's hard to explain."

"That will do, thanks for your help. You may go somewhere safe with M now if possible." Jimmy created a quick sketch with a few notes on his sketchpad and when he was done he recapped his pen.
He then turned back to the house.
"Time for investigation."
He ducked under the yellow tape and stepped toward the house. He examined the doorframe with great care and using a magnifying glass from his pocket...

Shun then was lead by his mother back in their house. This was all what M ordered them to do. M was sure that the house wouldn't explode today, because one explosion already occurred today and the plan for murderer is to do one explosion per day.
One hour passed with them sitting in their house until a news van came at the house with many reporters gathering around the house, they all started knocking the door rapidly trying to get some interview for the news with Shun. Soon the house door opened with mother covering Shun with a black blanket, his whole body was covered so not even feet would be seen. They walked to M with fast rate for a few second talk, then they soon sat into police car that later would drive to the police station.

Meanwhile M walked at the yellow tape watching Jimmy investigate the area. "I think it's pretty useless now... all the clues are probably gone along with the house in explosion. Do you think i should call the policemen to stop investigating this area?" M was talking to Jimmy.

"I'm not quite sure what to do actually at this point... No matter how good a murderer is, he always leaves behind a clue though." Jimmy spoke, as he stopped examining the doorframe and he turned to M.
"The bomb, or the device that was used to create the explosion would leave traces, for example."

"What kind of traces?" M looked at Jimmy with half opened eyes.

"Shrapnel, broken wire, ashes, DNA... That sort of thing." Jimmy replied.

"Yes... but the explosion would destroy it all, wouldn't it?" M looks with a evil smile at Jimmy. "Right now I'm interested in Shun's house..." M turned his head to Shun's house looking at it carefully.

This.
Was.
Not.
Good.
Jimmy had the worst feeling of his entire life as he stared at M, magnifying glass still in his hand.
"You."

"Yes?" M turned his head calmly to Jimmy and placed his hands in pockets of his jeans. M's face wasn't really serious, but more like a troublesome smile.

Jimmy stared, attempting to hide his horror but failing majorly.
"....Are very scary." Jimmy finished his sentence, gulping down the last few words. He then backed away from M, continuing to go into the house for more investigation. He turned to look around. Which area of the house was most blown apart?

"This spot here, sir." A policeman spoke pointing to a deep hole in ground that suffered the most damage. "At least that is a guess." The policeman said taking out a large notebook from shoulder bag and opening it few pages after beginning. "Since most of these houses here are basically the same... this is either the kitchen or bedroom." Policeman said reading what he had wrote on the paper. All the houses were 2 story large ones, the first floor had kitchen, living room and stairs. But second floor had bedrooms and toilet, bathroom.

"And the other houses, where were they destroyed from?" Jimmy asked the policeman.

"Same spot..." Policeman says looking more deeply in his note.
