Why usage of た and not ている in the following usage


I was watching a Japanese Drama, and I have questions regarding the usage of
Past tense (た) instead of Present Perfect (ている) in the following sentence.

In this Drama a person was looking for someone and as soon as he finds him
(both are present in the frame and he just finds him) he says, 見つけた (I found
him), rather than ている as in 見つけている (I have found him).

As per my understanding of the following articles on the Stackexchange, ている is
used to show both Continuous Aspect and Present Perfect (More or less
dependent upon whether the Verb is Punctual or Durative). When some fact of
the past is related and is being talked about in relation to present Present
perfect is used as per [@Naruto
san](https://japanese.stackexchange.com/questions/78871/usage-
of-%E3%81%A6%E3%81%84%E3%82%8B-in-punctual-verbs-in-japanese-and-the-concept-
of-present-perfect-in/78879#78879). Example 知る is used as 知っている, even though
we have learned (known) about him in the past, however we use ている as the focus
is not on the fact that we learnt it in the past but on the fact that whether
we know someone or not i.e. present.

Likewise, why was not ている used in 見つける. As in this case as well, even though
as soon as he found him the action was complete and it changed to past.
However, the focus is on the present i.e. the fact that he found him, and not
of that he found him in past, but just on the fact that he found him. So, in
this case, as per my understanding of the following resources. 見つけている should
have been used.

Question:

  1. Is my understanding correct?
  2. Should 見つけている be used instead of 見つけた, given the facts of the scene of the drama?

Resources used to gather this understanding:

state?](https://japanese.stackexchange.com/questions/3122/when-

I believe generally in Japanese immediately upon completing a task, you use
the _past tense_.

Examples range from

  * やった
  * できた
  * 出来上がった (said almost immediately after preparing a meal to essentially say “dinner’s ready.)
  * みつかった

Perhaps if a fair amount of time has elapsed (like a day or an entire week—I
suppose “fair amount of time” would depend on the urgency of the situation),
it might make sense to say 見つけている. (An urgent situation might be a parent with
Alzheimers who walked out of the house and no one know where they are.) But
immediately after the accomplishing something, no.
