Is tense proper in the sentence?

[nathesh2011]

Here is the man whom I think committed suicide.

[Bennevis]

Here is the man who I think committed suicide.

Here is the man who, I think, committed suicide.

Again, punctuation makes it easier.

[TheParser]

Here is the man whom I think committed suicide.

REMINDER: NOT A TEACHER

(1) I congratulate you on trying to use the word "whom." But I think that you have made

a mistake that some native speakers also make.

(2) Actually, the sentence is "Here is the man who committed suicide."

(a) According to many books, the words "I think" are just a comment "thrown into"

the sentence. They should be ignored in analysis.

(3) I think the tenses are correct. A police officer might point to a corpse and say

that sentence.
