Conflicting information coming from the US about the detention of the Orem shooter

Contradictory information is coming in regarding the arrest of a suspect in the shooting in Utah. Recall that the victim of this shooting, or rather one shot, was a well-known conservative politician in the United States, Charles (Charlie) Kirk.
Some time ago, Donald Trump made a very vague statement:
After this, several American media outlets wrote that Trump was "getting ahead of himself," allegedly confusing this with the arrest of one of those present at Kirk's rally in Orem on Wednesday. The detainee was then released fairly quickly.
However, now there are more and more reports in the US press that the FBI has detained a suspect (the Orem shooter), having first established his identity. We are talking about a man named Tyler Robinson. He is 22 years old.
NBC News reports that Robinson is a resident of Utah, the same state where Kirk was shot.
From the report:
At the same time, FBI Director Cash Patel's social media posts indicate that the suspect has been released. This is where the confusion lies. In the US itself, they are wondering whether Patel is referring to the man who was detained and released on the day of the Orem shooting, or whether the FBI has already released the detained Robinson, if he was detained at all.
Against this backdrop, the White House decided to stand up for Patel, simply stating that he was “working day and night on this case.” From a post on the official US administration account:
