I do not understand why Dmitri originally doubted that Smerdyakov murdered Fyodor but later changed his mind and thought Smerdyakov murdered Fyodor.
Be sure to go into www.sparknotes.com/lit and find this book under the B's -- then read the section called Analysis of Major Characters. Dmitri is at the bottom, but be sure to read about the others, too, so you understand the references made about Dmitri's character.
Please be sure to re-post if you need further help.

Dmitri originally doubted that Smerdyakov murdered Fyodor in the novel because he had an alibi for the time of the murder. However, he later changed his mind and believed that Smerdyakov was indeed the killer.
To understand this change in Dmitri's perspective, it is helpful to analyze his character and the events leading up to the murder. Reading the analysis of major characters in "The Brothers Karamazov" on SparkNotes is a great way to gain insight into Dmitri's motivations and actions.
By exploring the analysis of major characters on the SparkNotes website, you will gain a deeper understanding of Dmitri's personality, relationships, and circumstances. This analysis will provide important context for understanding why Dmitri initially doubted Smerdyakov's involvement in Fyodor's murder.
Once you have read the analysis section, you will find a clearer explanation of why Dmitri had doubts about Smerdyakov's guilt in the first place, as well as the factors that led him to ultimately change his mind and suspect Smerdyakov.
