The horizontal bar

It was early and dank autumn morning. It happens so often at the end of October. Police has been working on the crime scene of the accident for an hour. Old dumpsters between the garages looked particularly dull this time. Not far from the dumpsters, a man of medium height, in a gray jacket and black pants, lay on his stomach; his shoes very good and expensive were stained with dirt. Not far from him lay a metal pipe with traces of blood on the end. The police were documenting everything, and one of them went to a small group of people nearby.
– Any of you witnesses to what happened here? Maybe you heard or saw something? – asked the man in the jacket.
– I saw! I called an ambulance! – replied a tall woman in a frayed raincoat and old boots.
– You need to come with me, – the police officer invited the woman to a minibus parked next to one of the garages.
When the policeman got in the car, he took off his cap and took out some sort of form.
Well, tell me everything, please! – he asked calmly and at the same time firmly.
– My shift ended late today, and we had been arrived at the bus stop in 5:00 in the morning. I rarely go home this way. There has never been a lantern on the garbage dump, it is very dark, it is lit only by the light from the windows of the houses. As I was getting out of the bus, I noticed that this way the neighbor went. Well, I thought that now it would be less unpleasant to pass there.
– Is this man your neighbor? – the police officer asked.
– We live in neighboring houses, – the woman nodded her head vigorously.
– What is his name? – asked the policeman.
– I don’t know his name, we haven’t talked. They somehow don’t social, – the woman's face twisted in a scornful grimace.
– You followed him, what happened next? – the policeman turned the pen in his hand, waiting for him to continue.
– When I followed him, I saw something moving in the dim light next to the dumpsters. I stopped. At that moment, one of the neighbors woke up and lit a light in his apartment. It became clearer visible that three people grabbed one, and the fourth one found a stick from an old horizontal bar and hit neighbor. I was more dead than alive from surprise and horror. The neighbor fell, and the four of them began to rummage in his pockets. At that moment my phone vibrated. Apparently, a text message came, and I realized that I needed to call the police. I called.
– Did you get a look at the attackers? – the policeman continued to ask without raising his head.
– No, but I thought they were all very young, – the woman noted.
– Do you remember what they said? – the policeman continued.
– I couldn't make out what they were saying, I just thought they were teenagers.
– But you said that one of them grabbed a stick from the horizontal bar. How do you know so much about it? Maybe he grabbed something other? – the policeman raised his head and stared at the woman. She cringed under his gaze.
– No! This is definitely a stick from the horizontal bar! This stick has been lying there in the trash against the wall for so many years useless to anyone. We have had a huge horizontal bar in our yard since Soviet times. Well, there was a swing on one side, they broke down a long time ago, and on the other side there was a horizontal bar. So comfortable, both children and adult men were pull-ups, – woman relaxed and smiled, – Children, you know, dragged old mattresses in there and trained on this horizontal bar all day. It's amazing how they don't get tired. And we grew up with this horizontal bar too. In our yard, of course, they had put these new horizontal bars, but they are so small and uncomfortable that teenagers have nowhere to put themselves. Previously, at least on the horizontal bar trained, and now more and more smoke around the corner. They have nothing to do.
The policeman, apparently carried away by the woman's story, leaned back in his seat.
– Well, probably, teenagers broke this horizontal bar, – the policeman said sarcastically.
– What are you saying! No! This neighbor sawed it down himself about five years ago! – the woman protested.
The policeman raised his eyebrows.
– What for? – the policeman asked.
– I don’t know. It seems to me that he did not like that teenagers make noise on the horizontal bar and that mattresses were always lying under the horizontal bar.
On the evening of the same day, a policeman found a broken old horizontal bar in that yard. He took out a cigarette, lit it, then pulled his phone out of his pocket and opened the photo, which clearly showed the dirty bar of the horizontal bar.
Several months later, the teenagers were found. The reason for the reason for the attack on the neighbor was boredom and craving for profit.
