A US Marine who allegedly raped a young woman before conspiring with a fellow jarhead to cover it up has faced the first day of his trial alongside his “friend and gym buddy”.

Lester Rodriguez Turcios pleaded not guilty in the Supreme Court to rape, aggravated assault and attempting and conspiring to pervert the course of justice, while fellow marine Juan Martinezjaramillo pleaded not guilty to conspiracy.

In his opening address to jurors on Monday, Crown prosecutor Damien Jones quoted directly from the 19-year-old alleged victim following the incident on May 27 last year.

“I woke up to him pushing himself inside me, I had no underwear on, I was like ‘uh, what the f--k?’, I’ve tried pushing him off me quite a bit but he had kind of pinned me down."

The woman reported the alleged assault six days later and police asked Martinezjaramillo to make a statement as a potential witness on June 21. Investigators also obtained a warrant to seize Turcios’ mobile phone, which revealed conversations between the two marines “as to what was going to be said in the interview”.
