This equals her in the number of medals earned during single Olympic games with the legendary Polish athlete Irena Szewińska.
In the final she improved her own world record with a time of 2:05.61 to beat Australian Jessicah Schipper by only 0.04 seconds.
After the race it was disputed that Jędrzejczak touched the finishing wall with only one hand (with video replays confirming this), which according to International Swimming Federation rules would be grounds for an automatic disqualification.
On 13 December 2007, on her 24th birthday, Jędrzejczak broke the world record for the 200 metre women's butterfly (short course) with a time of 2:03.53.
After the race Jędrzejczak revealed, that during the pre-Olympic trials in Athens in June she had declared that if she won a gold medal in the Olympics, she would auction it off and hand the proceeds to a charity helping children suffering from leukemia.
The results of the internet auction were announced on 19 December 2004 with Victoria Cymes, a Polish food company, turning out to be the highest bidder with 257,550 zlotys (about 82,437 USD).
The 2005 Chrysler 300C HEMI which she was driving crashed head-on into a tree, after a botched attempt to overtake several long-haul trucks at excessive speed during bad weather conditions.
The prosecutors initially proposed Jędrzejczak an agreement which would lead to a sentence of 2 years imprisonment in suspension.
Jędrzejczak refused the agreement and strongly pressed for an acquittal, stating that she was already punished enough by her brother's death.
During the trial the prosecution highlighted the fact that Jędrzejczak was an inexperienced driver and her driving at the moment of the fatal accident was reckless.
[citation needed] In 2006, she returned to competitive swimming and competed in European Championships in Budapest, finishing first in 200 m freestyle and 200 m butterfly as well as sechond in 4×200 m relay.
Although both Jędrzejczak and her trainer Paweł Słomiński stated that Eindhoven results were "just an accident", 2008 Summer Olympics proved otherwise.
