OK, so here's what has been told so far by the media.
Dawid was a 5-year-old boy of Polish-Russian nationality, his mother was Russian and his father was Polish of Kazakh origin. They had not been living together for 3 weeks before the father's suicide. Dawid's mother moved from him to Warsaw, taking the boy with her. She was going to divorce her husband but did not start the procedure so far.
The father's co-workers and friends told the newspapers that he was a calm man, he seemed to be a good father, but had problems with hazard that caused huge debts. This probably was the reason behind his conflict with his wife. 2 weeks before the suicide, he stopped going to work for unknown reason. The information about the hazard and debts was not confirmed by the police, yet it appeared in media.
There was also the information that Dawid's mother reported to the police that her husband was mentally abusing her. However, there are no information about any physical abuse to her or Dawid before.
Other thing that leaked to the media is that father was married for second time. After the divorce, his first wife went to Ukraine with their child.
The timeline:
10th July
17:00 - Dawid's father picks the boy from his grandparents - that's when the boy is seen the last time.
17:28 - Father is driving to Warsaw through Chrzanow Duzy. He stops the car for a few minutes near the Konotopa highway junction.
about 18:30 - F. goes back to Warsaw. On the way back, he stops for 40 minutes near the Konotopa highway junction again. He is talking with wife on the phone and she tells him about her divorce plans.
18:34 - F. sends the last text message to mother. He writes that she "will never see her child again". It's the last time they get in touch.
19:34 - F. goes by car to Grodzisk Mazowiecki through Chrzanow Duzy.
about 20:00 - F. pasks 3 kilometres from the railway tracks, near the church. He goes to a church and prays.
20:52 - F. dies hit by the train. According to the train driver, it was a suicide.
In the meantime Dawid's mother, after attempts to contact the father again by phone, drives to his home by herself, but he is not home.
11th July
about midnight - Mother is going to the police office to report the boy is missing.
2 a.m. - The car is found.
The timeline was based on the monitoring from cameras and data from GPS. However, the exact time when the boy left the car is not known. Father switched off his phone a few times during this time, and the videos from cameras couldn't show the child.
I read that in Warsaw father and Dawid were observing the planes near the airport. Mother talked with Dawid by phone when he was still in the car and nothing was wrong, according to her.
I also read that the mother contacted the police after midnight, not earlier, because she did not believe that her husband could harm the child. She thought about his message that "he was being malicious again". That's why she tried to pick up the boy by herself.
There were some rumours in a newspaper about the blood and urine found in the father's car or on his clothes, but the police officially denied these, saying that they don't have the results of the examination of the car and clothes. The phone was also found with the father. His clothes and phone are severely damaged and need time to be examined.
The search lasted for 10 days and was very intensive, with the use of drones, helicopters, dogs and specialistic equipment.
2 hours ago I read that the police has just announced they found the body in the water, 5 kilometres from father's home. They are almost sure it is Dawid. This has to be confirmed yet by his family, but condolences for Dawid's family appeared on the official police profile. The prosecutor will announce more details about his death when it is possible. Investigation will continue.
So sad to write this. A few hours ago, when I wrote here for the first time, the search was still in action. Poor little boy
