A former Google programmer was sentenced, according to a report, to 14 months in prison for threatening to "kill" U.S. Supreme Court Chief Justice John Roberts in an expletive-laden voicemail.

Neal Brij Sidhwaney, 43, of Fernandina Beach, Florida, pleaded guilty in December to transmitting an interstate threat to kill, according to federal prosecutors.

In July, Sidhwaney called the Supreme Court in Washington, D.C., identified himself, and repeatedly threatened to kill Roberts in a voicemail.

"I will f–– kill you... go tell the f–– Deputy U.S. Marshals you f–– p––. I will f––talk to them and then I'll f–– come kill you anyways you f–– c––," Sidhwaney said, according to court documents.

Roberts wasn't named in the documents, but was identified in a psychological evaluation, which indicated Sidhwaney suffered from a provisional delusional disorder and unspecified schizophrenia and other psychotic disorder.

Sidhwaney originally faced up to five years in prison.
