Man gets life sentence in strangulation murder of Valley woman turned prostitute

An Austin man received a life sentence Tuesday for the May 2009 strangulation murder of Amy Dickey,  a McAllen High School graduate turned prostitute.

Jurors convicted Nathaniel Briscoe, 30, of murder and tampering with evidence Tuesday in Travis County state District Court.

Austin police arrested Briscoe in May 2009 for his connection to the murder of Dickey, a 28-year-old who graduated from McAllen High School in 1999.

A landscaping crew discovered Dickey’s body buried in a wooded area in southwest Austin the morning of May 21, 2009. The crew told Austin police investigators they noticed her hand poking out from beneath a pile of debris.

Dickey’s fingerprints linked her to a burglary earlier that month, and the other suspect in the case said she had been working as a prostitute. Call records from Dickey’s cell phone led detectives to Briscoe, who was arrested on suspicion of her murder.

Steven Brand, the Travis County assistant district attorney who prosecuted the case, said a three-hour interview Briscoe gave to police investigators implicated him in the case.

In the footage, Briscoe told investigators that Dickey had asked for him to “lighten up on my neck” while they had sex at his apartment, Brand said. Briscoe told police he choked her for about five minutes before he stopped, later claiming that Dickey left his apartment.

Testimony from a medical examiner revealed that a person can fall unconscious after about 20 seconds of strangling and it generally takes about three minutes for someone to die, Brand said.

“It just added up,” the prosecutor said of Briscoe’s guilt in the case. “He didn’t confess, but he certainly put himself in an unenviable position.”

Briscoe showed little emotion when he learned of the life sentence Tuesday afternoon, the Austin American-Statesman reported.

Evidence presented during sentencing included how Briscoe had spent a year in federal prison for possessing a live grenade and how he had improper sexual contact with a 7-year-old relative when he was 19, Brand said.

“You factor all that into the equation, you’ve got a live grenade, taking advantage of a 7-year-old … he’s pretty dangerous,” he said. “I’m just proud the system worked.”

Briscoe received a 25-year sentence on the tampering conviction that will run concurrently with the murder sentence. He will become eligible for parole May 25, 2039.
