St. Lucie County Sheriff Mascara announces arrest of co-habitant in Rachel Robles case
St. Lucie County Sheriff's detectives concluded a two-month investigation today, charging the co-habitant of 37-year-old Rachel Robles with leaving the scene of a traffic accident involving a death on May 11, according to Sheriff Ken J. Mascara.

"Mark Anthony Terrien, 33, of 324 Godwin Road, lived with Ms. Robles for 17 years, and the couple had three children," Sheriff Mascara said. "Mr. Terrien called 9-1-1 the morning of May 11, claiming Ms. Robles was missing when he woke up to go to work. He later admitted that this wasn't true."

Terrien eventually told detectives that Ms. Robles jumped out of the couple's 2008 Saturn Outlook S.U.V. while he was driving. He admitted to stopping, seeing her body beside the road, and remaining there for five minutes during which time she didn't move, and he knew she was dead.

He told investigators that he saw the headlights of an approaching vehicle, got into the S.U.V. and drove away because he was drunk. Passersby discovered the body on Angle Road near Godwin Road and called 9-1-1.

Terrien said he sent his children to Georgia with his mother, who also lived at the Terrien-Robles home, in the S.U.V. he was driving during the early morning hours of May 11. He said he sent the children away because he didn't want them to see him being arrested.

Based on the autopsy results, the physical evidence, Terrien's accounts of the incident, and after consultation with the State Attorney's Office, the Sheriff's Office obtained an arrest warrant for the first-degree felony of leaving the scene of a traffic accident involving a death, Sheriff Mascara said.

The maximum prison term for a conviction on that charge is 30 years.

This afternoon, deputies booked Terrien into the county jail under $50,000 bond.
