This question is not complete, it lacks some information for me to correctly answer it.
The evidence may not be sufficient to convict the suspect in the case.
Suspect. As I "I suspect he is wrong" or "we suspected that was not the case"
No, the suspect's admission to guilt does not necessarily provide conclusive evidence in the case.
The police suspect him of being involved in the robbery. She found some suspicious items in his bag and began to suspect his intentions. After conducting an investigation, the detectives were able to identify the main suspect in the case.
If the suspect remains identifiable then there is no consequence.
The suspect
There were 24 suspects. The first suspect was Montague John Druitt.
Noun: The main suspect was Mr. Collington who was acting particularly suspicious. Verb: I suspect that Tina will be the earliest to come to the party.
Miranda v Arizona was the case that set the precedent that verbal warnings must be given to a suspect during arrest.
The suspect in the same case he is prosecuting? It might make a good plot for a fiction book and technically it IS possible, but I seriously doubt it.
I suspect you mean maladroit, in which case it means inept or clumsy.
Not necessarily.
