OPINION
By the Court,
While the police were at appellant’s trailer, he called by telephone to speak to his girlfriend, and spoke to an investigating officer. He was made aware that he was under suspicion, and he thereupon agreed to talk to the officers. Without keeping this promise, however, appellant immediately fled this jurisdiction by bus, and returned to Florida where he lived for five years under an assumed name. A few weeks after his flight, appellant’s girlfriend also disappeared from Nevada, and lived with appellant in Florida as his wife, under an assumed name, until he was apprehended in January of 1986. Thereupon, he was tried and convicted of murder, attempted murder, and two counts of robbery with the use of a deadly weapon. He was sentenced to life without the possibility of parole for murder, plus forty consecutive years for attempted murder, and two concurrent thirty-year terms for robbery with a deadly weapon. Appellant appeals from said judgment and sentence.
On appeal, appellant contends that numerous items of evidence were lost in the years between the crime and his arrest, thereby depriving him of a fair trial.

We disagree. When a defendant seeks reversal upon the basis of lost evidence, he must show
either governmental bad faith, connivance, or prejudice. Rogers v. State,
We also see no exculpatory value in evidence of the body temperature of the deceased victim, particularly in the instant case where one victim survived the shooting. In addition, an expert witness testified that even under ideal conditions he may not have been able to determine the exact time of Vivian Grady’s death. Finally, although we agree that certain police actions (e.g., throwing away the contents of a glass found at the scene and taping over a videotape of the scene) may not constitute exemplary investigative techniques, appellant has not persuaded us either of the exculpatory value of the evidence, or of any prejudice resulting from its loss. Therefore, appellant has failed to show that the absence of this evidence deprived him of a fair trial.
Third, appellant contends that the prosecutor committed misconduct by asking allegedly irrelevant prejudicial questions about
the mafia. Although we are concerned about the relevancy of the questions and the possibility of prejudice, we note that the issue has not been adequately briefed. It is appellant’s responsibility to present relevant authority and cogent argument; issues not so presented need not be addressed by this court.

Carson v. Sheriff,
Finally, we note that there is overwhelming evidence of appellant’s guilt. Grady stated several times that “Joe” shot him, and he gave a detailed description of his assailant which matches appellant’s description. Appellant’s counsel has not questioned the propriety of admitting these statements. However, they undoubtedly figured heavily in the jury’s determination of guilt. While it might be argued that it was inappropriate for the district court to assume that Grady embraced a fear of dying, and thus to admit the statements as dying declarations,

these statements could certainly be admitted under NRS 51.315(1).

We have previously held that a statement could be admitted under NRS 51.315 where the persons making the statement had no involvement with the police, the defendant, or the victims; where neither the declarants nor the police had any apparent motive to lie; where the declarants were unavailable for trial; and where the statement, in its nature, was of a relatively simple kind which could be recorded with little prospect of later misinterpretation.
See
Johnstone v. State,
A statement is not excluded by the hearsay rule if:
(1) Its nature and the special circumstances under which it was made offer strong assurances of accuracy; and
(b) The declarant is unavailable as a witness.
In addition to Grady’s statement, the record is replete with other evidence of appellant’s guilt. For example, it is well established that although evidence of flight is not in and of itself sufficient to support a conviction, it is circumstantial evidence which can be considered with other
We have considered appellant’s remaining contentions, and conclude they are without merit. Accordingly, we affirm the judgment of conviction and the sentence.
Notes
These two statements, and a third and fourth account by Grady, were admitted into evidence at trial.
Appellant also argues that the State erred in not testing clothing for gunshot residue. We note that the clothing itself was preserved and was available for testing; however, appellant failed to conduct any tests.
NRS 51.335 states:
A statement made by a declarant while believing that his death was imminent is not inadmissable under the hearsay rule if the declarant is unavailable as a witness.
NRS 51.315(1) states:
