BENHAM, Justice.

Appellant Craig Armstead was convicted of murder, aggravated assault, possession of a weapon during the commission of a crime, and unlawful eavesdropping and surveillance, all of which were crimes he committed in his workplace, including the stabbing death of his coworker Kerri Harris.1 The evidence at trial showed appellant placed a video camera in a women's restroom at his workplace and commenced a scheme whereby he would record his female co-workers using the restroom, retrieve the tapes and replace them after-hours, and take the tapes home where he watched and stored them. During his employment, appellant attempted to date the victim but she rebuffed him. On the day of her death, the victim and another woman had reported to human resources that they found a camera in the women's restroom. Although the women did not know who had placed the camera in the ladies' room, appellant believed he had been discovered. Throughout the day, appellant became increasingly agitated, especially when he noticed police had been called to the workplace. He obtained a knife from a test kitchen in the facility and waited a few hours for the victim to return from a meeting. As soon as she returned to her office, he stabbed her in the back and neck. Another employee, who had heard noises of someone being injured, followed the sounds and saw appellant leaving the victim's office. Appellant fled the premises, but was arrested soon thereafter. The victim died at the scene.

At trial, it was shown appellant had previously been convicted of manslaughter in the early 1990s in New Jersey for killing an ex-girlfriend by hitting her with a hammer and strangling her to death. Appellant was released from prison in 1999 and relocated to Georgia shortly thereafter. In 2000, appellant was convicted in Georgia and received a one-year sentence for watching a woman in a public restroom. After serving that sentence, he began working at the employer at whose workplace he committed the crimes at issue. Appellant's defense at trial was that he was not guilty by reason of insanity because he was operating under a delusional compulsion. Specifically, appellant's expert psychologist Dr. Eugene Emory testified appellant suffered from intermittent psychosis and, at the time he killed the victim, was operating under a delusional compulsion that the victim was a bad person who needed to be eliminated.

1. The evidence adduced at trial and summarized above was sufficient to authorize a rational trier of fact to find appellant guilty beyond a reasonable doubt of the crimes for which he was convicted. Jackson v. Virginia, 443 U.S. 307, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979); Alvelo v. State, 290 Ga. 609(3), 724 S.E.2d 377 (2012).

2. As his sole enumeration of error, appellant contends the trial court erred when it denied his motion in limine and allowed Dr. William Brickhouse, Director of Mental Health at the DeKalb County Jail, to testify at trial. The facts show appellant was given a mental health evaluation shortly after his booking into the jail. Because he was "behaving bizarrely" and expressed suicidal ideation, he was housed on a psychiatric ward inside the jail to be further evaluated by Dr. Brickhouse and his staff. Appellant was eventually released into the general prison population, but continued to be monitored and evaluated by Dr. Brickhouse and approximately six psychiatrists during his pretrial incarceration spanning just over two years from June 2008 to July 2010. On August 4, 2010, appellant filed notice of his intent to plead not guilty by reason of insanity. Two days later, the State obtained appellant's jail mental health records by subpoena. On August 17, 2010, appellant filed a motion in limine seeking to exclude Dr. Brickhouse's testimony and portions of the testimony of the court-appointed psychologist Dr. Pamela Eilender that were based on his jail mental health records. On appeal, appellant contends Dr. Brickhouse's testimony should have been excluded2 because the State improperly obtained his jail mental health records by subpoena and without appellant's consent (i.e., a release) or warrant in violation of the Georgia Constitution and in violation of the Fourth Amendment of the federal constitution. For the reasons set forth below, we affirm the trial court's denial of appellant's motion in limine and the denial of appellant's motion for new trial.

(a) This Court has held that Georgia citizens enjoy a state constitutional right of privacy to their medical records. King v. State, 272 Ga. 788, 790, 535 S.E.2d 492 (2000). In addition, the Georgia legislature has created statutory privileges prohibiting the disclosure of confidential communications between a patient and his psychiatrist, psychologist, or other similar mental healthcare professional. OCGA §§ 24-9-21 (2012)3 and 43-39-16.4 We have held, however, that the privacy enjoyed by citizens as to their medical records, including mental health records, is not absolute (King, supra, 272 Ga. at 793, 535 S.E.2d 492)5 and any statutory privilege or right of privacy in such records may be waived by the accused, in particular if the accused affirmatively places his mental capacity in issue in a civil or criminal proceeding. See OCGA § 24-9-40(a) (2012);6 Moreland v. Austin, 284 Ga. 730, 732, 670 S.E.2d 68 (2008) ("Georgia law is clear that a plaintiff waives his right of privacy with regard to medical records that are relevant to a medical condition the plaintiff placed in issue in a civil or criminal proceeding."); Rogers v. State, 282 Ga. 659(6)(b), 653 S.E.2d 31 (2007); Perkinson v. State, 279 Ga. 232(6), 610 S.E.2d 533 (2005); Trammel v. Bradberry, 256 Ga.App. 412, 424(6), 568 S.E.2d 715 (2002) (raising defense of insanity waives statutory privilege protecting disclosure from psychiatrist-patient relationship). Here, it is undisputed appellant placed his mental capacity in issue when he filed a notice of intent to pursue a defense of not guilty by reason of insanity. This constituted a waiver of any state constitutional right of privacy or statutory privilege in his mental health records. See id. The record shows the State did not subpoena any of appellant's jailhouse mental health records until after appellant filed his notice, or, alternatively stated, until after appellant waived his privacy rights in the records. Accordingly, the State was not prohibited from obtaining the records by subpoena and the trial court did not err when it denied appellant's motion in limine and allowed Dr. Brickhouse to testify at trial.

(b) Under these circumstances, appellant also cannot show any violation of the Fourth Amendment's prohibition against unlawful searches and seizures. Pretrial detainees have a substantially diminished expectation of privacy for purposes of the Fourth Amendment. State v. Henderson, 271 Ga. 264(2), 517 S.E.2d 61 (1999). In a prison setting, the maintenance of "institutional security and internal order" take precedent over any expectation of privacy concerning an incarcerated individual. Id. at 265, 517 S.E.2d 61. Here, the facts show appellant did not initiate any treatment from Dr. Brickhouse and his staff for mental illness. Rather, upon his arrest appellant was initially subject to a mental health screen in accordance with jail protocol and soon thereafter was placed on the jail's psychiatric ward and put on a suicide watch because he was "behaving bizarrely." After appellant was placed in the general prison population, Dr. Brickhouse and his staff continued to monitor and meet with appellant because appellant would state that he had urges to hurt himself and/or others.7 For example, during his pretrial incarceration appellant cut himself superficially with a razor and attempted to rush a prison guard. The primary purpose of Dr. Brickhouse's actions, and the actions of his staff, was to control appellant's behavior for the safety of the prison as opposed to caring for appellant's mental health.8 As such, appellant had a diminished expectation of privacy with regard to his jailhouse mental health records. Id. When appellant announced his intent to assert an insanity defense, he waived what little expectation of privacy he had with regard to his communications with Dr. Brickhouse and his staff. As such, appellant's Fourth Amendment rights were not violated when the State subpoenaed his jail mental health records and the trial court did not err in denying the motion in limine or in denying the motion for new trial.

Judgment affirmed.
