If "Maria Tapia" appears to simply be a mistaken entry with no life on the internet, then merging her with a more appropriate profile, preferably the person she is really supposed to be -- will make the profile go away.
BUT -- if "Maria Tapia" exists on Geni or Ancestry or elsewhere on the internet, then the profile should be retained because if she is made to go away, Murphy's Law says another well-meaning person will re-create her.
I have already added the {{Uncertain Existence}} template to her profile. If you think she has a life in popular genealogy, then make this your one-week notice that she will be marked {{Disproven Existence}}. Then the Disproven Existence Project will manage her profile, all links to parents, spouses, and children will be cut (because people who never existed don't have relatives), and she won't be part of the global WikiTree, but if anyone tries to re-create her they will see that there is already a profile, and they will find the record of your good research!
