The above is correct but in addition, for a parent, one tears on the left, the side of the heart. For the other 5 relatives (brother, sister, spouse, or [R"L,] son or daughter), one tears on the right side.

Also, it is inappropriate to show such an intense form of mourning on Shabbos or after the Shiva. To clarify, this is only appropriate for the shiva, unless the Kri'ah was never done (or the ribbon was used, which is insufficient.) In a case where someone did not do the Kri'ah, either because he wasn't aware of the requirement or just heard about the loss after the Shiva was concluded, he should do the Kri'ah on that day only.
