The evidence at trial was largely derived from statements Beck made to the police after his arrest. Beck stated that he planned to kill Miller, his former employer. On June 6, 1995 Beck broke into the house shared by the victims and waited for them to return home. Marks returned home first and Beck shot her in the basement of the house. Beck stated that he tried to make it look as if she had also been raped, but a medical examiner asserted that she had actually been raped. Later that afternoon, Beck shot Miller and placed his body in Kaplan's apartment. When Kaplan returned home, Beck shot him and stabbed him in the head.

The trial court accepted Beck's guilty pleas and, after a sentencing hearing, sentenced him to death in each of the three murders. Between the time of the guilty pleas and the sentencing hearing, the trial judge received numerous victim impact letters from the family and friends of the victims. 

On appeal, the Supreme Court of Virginia affirmed the convictions and sentences. The court held that victim impact evidence from persons other than family members of the victims is admissible, and that the record showed that the trial judge did not abuse his discretion in considering the statements. In 1997, the United States Supreme Court denied Beck's petition for a writ of certiorari.

In May, 1999 Beck was involved in an incident at Sussex I State Prison culminating in his being tied down in four-point restraints. Prison officials allege that Beck was restrained after he became disruptive and verbally abused the staff. Another inmate, however, claims that the staff assaulted Beck in his cell after he argued with a nurse.

Christopher Beck entered death row on August 15, 1996 and was executed on October 18, 2001.
