His family attempted to have him admitted into a hospital for treatment in May 1999 after a manic episode, but he refused their assistance.
Chervenka phoned his sister during the evening hours of May 28, 1999 from his home in Phoenix, Arizona. He apparently threatened members of his family during the conversation. His sister contacted the authorities after terminating the call, but law enforcement said they could not become involved, as Chervenka had not make a specific threat against anyone.
Chervenka apparently made several more phone calls, then departed from his residence that night. He has never been heard from again.
Authorities searched Chervenka's apartment 11 days after his disappearance. An open notebook was on the table, along with a glass of soda and a Bible. There was no sign of him.

A missing person is a person who has disappeared and whose status as alive or dead cannot be confirmed as their location and condition are not known. A person may go missing through a voluntary disappearance, or else due to an accident, crime, death in a location where they cannot be found (such as at sea), or many other reasons. In most parts of the world, a missing person will usually be found quickly. While criminal abductions are some of the most widely reported missing person cases, these account for only 2–5% of missing children in Europe.
By contrast, some missing person cases remain unresolved for many years. Laws related to these cases are often complex since, in many jurisdictions, relatives and third parties may not deal with a person's assets until their death is considered proven by law and a formal death certificate issued. The situation, uncertainties, and lack of closure or a funeral resulting when a person goes missing may be extremely painful with long-lasting effects on family and friends.
Several organizations seek to connect, share best practices, and disseminate information and imAge at the time of disappearance: s of missing children to improve the effectiveness of missing children investigations, including the International Commission on Missing Persons, the International Centre for Missing & Exploited Children (ICMEC), as well as national organizations, including the National Center for Missing & Exploited Children in the US, Missing People in the UK, Child Focus in Belgium, and The Smile of the Child in Greece.
