問問有關英文時態問題

如果附加
Mary and Tom have just died a few minutes ago.
就perfect。

就算不講出確定的死亡時間，要再詳細形容他們可以講：
Mary and Tom have just died only a few minutes apart a few minutes ago.

I think it is ok.(maybe)

Tom and Mary all died off one by one.No Problem.

"Mary and Tom have just died." ~ 對
"Mary and Tom have just died a few minutes ago." ~ 錯
....... died.a a few minutes (days/years ...etc) ago. ~ 要用 past simple tense

知識長知足常樂非常客氣
I know without a shadow of a doubt that Jenkin is wrong.
錯即是錯, 人誰無過?
攪笑是將發問者對的句子改為錯的句子

Jenkin，想請問一下如果句子中用了 "a few minutes ago" 是否仍可用 present perfect tense?
