Need help with movie title

I saw this movie in 1980’s. From what I can remember, there is a guy that is remembering an event where he saw a kid being beat up by two men. The men hit the boy in the eye with a wrench or pipe. Then they throw him in the water.

Do you remember any other details?

Does it happen to be on this list? https://www.imdb.com/search/title/?keywords=child-killed&explore=keywords&title_type=feature,tv_movie&release_date=1975-01-01,1990-12-31&sort=release_date,asc
