Melvin Warness appeals his conviction for second degree rape. He argues that (1) evidence was wrongly admitted concerning statements he made in response to police questioning, and (2) certain opinion testimony of an expert *638 witness was admitted without a proper foundation. We affirm because Warness did not invoke his Fifth Amendment right to counsel prior to making statements to police and the expert testimony was properly admitted.
Facts
Investigating a rape complaint, a police officer contacted Warness at his home. The officer made it clear to Warness that he was not under arrest, did not have to speak to the police, and was free to leave at any time. Sometime after the conversation began, Warness stated he did not want to talk any further without an attorney. The officer ended the conversation and left.
Approximately 1 month after the incident a warrant was issued for Warness’ arrest. After arresting Warness, a second police officer informed him of his Miranda 1 rights. Warness acknowledged his rights and signed a written waiver. Warness then made statements to the effect that he had not had intercourse with the alleged victim on the evening in question. Warness later invoked his right to counsel.
Prior to trial, Warness objected to the admission of his statements to the second officer, arguing that he invoked his right to counsel regarding the rape investigation during the first meeting with police. The trial court allowed the statements, ruling that Warness’ Fifth Amendment rights had not attached at the first meeting.
Warness declined to testify at trial and stipulated to having had intercourse with the victim on the evening in question. During the testimony of the interrogating officer, Warness’ statements that he had not had intercourse were elicited.
The victim had described to police a wound she inflicted on Warness by biting his left hand as he held it over her mouth. Dr. Bell, a forensic odontologist, was permitted to testify at trial that marks on Warness’ hand, evidenced by photographs taken at the time of his arrest, were consistent with a bite *639 mark. Dr. Bell noted that his opinion could not be conclusive based on the evidence he was provided. Warness objected to this testimony prior to trial. The trial court admitted the testimony, ruling that the lack of certainty went to the weight of the evidence and not to its admissibility.
Warness was found guilty of second degree rape.
I
Warness argues that his statements made to the police after waiving his
Miranda
rights should not have been admitted at trial because he had previously invoked his right to counsel. In order to protect a defendant’s Fifth Amendment right against compelled self-incrimination,
2
the United States Supreme Court determined in
Miranda v. Arizona, supra,
that a suspect must be given the right to remain silent and the right to the presence of counsel during any custodial interrogation. The police officer or prosecutor must inform the suspect of these rights prior to interrogating, and the suspect may either invoke or waive them. If a suspect invokes the right to silence the police must cease interrogation until a later time. The Supreme Court later held that once the right to counsel is invoked the police cannot initiate further interrogation or seek a waiver until the suspect has an opportunity to meet with counsel.
Edwards v. Arizona,
The
Miranda
protection is premised on custodial interrogation. Both factors must be present for
Miranda
protection to attach. A suspect who is not in custody does not have
Miranda
rights.
See Stansbury v. California,
Warness attempted to invoke his right to counsel during a noncustodial conversation with a police officer. At that time his right to counsel had not yet attached. Nevertheless, Warness argues that this invocation had the effect of prohibiting any future custodial interrogation.
The United States Supreme Court has yet to address this issue.
We have in fact never held that a person can invoke his Miranda rights anticipatorily, in a context other than "custodial interrogation” .... If the Miranda right to counsel can be invoked at a preliminary hearing, it could be argued, there is no logical reason why it could not be invoked by a letter prior to arrest, or indeed even prior to identification as a suspect. Most rights must be asserted when the government seeks to take the action they protect against. The fact that we have allowed the Miranda right to counsel, once asserted, to be effective with respect to future custodial interrogation does not necessarily mean that we will allow it to be asserted initially outside the context of custodial interrogation, with similar future effect.
McNeil v. Wisconsin,
We find these cases persuasive, and hold that the Fifth Amendment right to counsel cannot be invoked by a person who is not in custody. The right is not itself provided by the constitution, but is designed to counteract the coercion inherent in custodial interrogations and protect the constitutional right to be free from compelled self-incrimination.
See Davis v. United States,
Warness argues he was in custody for purposes of
Miranda-Edwards
protection during his initial meeting with police because he was the focus of their investigation. In making this argument, Warness acknowledges that he is asking this court to ignore recent state Supreme Court precedent regarding the definition of custody. In
State v. Harris,
Warness does not cite recent United States Supreme Court precedent also on point. In
Stansbury v. California, supra,
the court rejected California’s definition of custody for purposes of
Miranda
protection. California had applied a definition of custody which included the situation Warness asks for: when the investigation has focused on the subject.
Stansbury,
In this case, Warness was approached at his home and was able to end his contact with police at will. The officer made clear to Warness that he did not have to talk and was free to end the conversation at any time. Warness could not reasonably have believed that his freedom of action was restricted. Warness was not in custody during his first meeting with police and was, therefore, not able to invoke his Fifth Amendment right to counsel.
II
Finally, Warness argues the State’s expert witness, Dr. Bell, should not have been allowed to testify that the marks on Warness’ hand were consistent with a bite from the victim. "The decision whether or not to admit expert opinion evidence is within the discretion of the trial court and will not be disturbed absent a showing of an abuse of that discretion.”
State v. Swan,
Warness takes the position that an expert’s opinion is only relevant if it is conclusive. In this case, the expert testified that his opinion was not conclusive, but the evidence was consistent with the alleged victim’s assertion that she had bitten Warness.
*643
Expert testimony which is merely speculative is not admissible. However, inadmissible speculation is not the same as a legitimate opinion regarding what "could be” the truth, so long as that opinion can be stated with the requisite reasonable scientific probability.

In
State v. Lord,
[Ejxpert testimony couched in terms of "could have”, "possible”, or "similar” is uniformly admitted at trial. The lack of certainty goes to the weight to be given the testimony, not to its admissibility. This is so, in part, because the scientific process involved often allows no more certain testimony.
Lord,
As long as the scientific methods used to form the opinion are generally accepted within the relevant community, an expert’s lack of certainty does not render the evidence inadmissible.
Lord,
Warness also argues the expert testimony was more prejudicial than probative. However, Warness was able to counter the expert opinion with several witnesses who saw no marks on Warness’ hand around the time of the alleged incident, and with evidence that Warness had been working on a car, which could have left similar marks, before any photographs were taken of his hand. The expert himself admitted that his opinion was only that the marks were of a size and shape consistent with a bite by the victim. The trial *644 court’s decision to admit the testimony was well within its discretion.
Affirmed.
