Lawyer Andrew Haynal announced Friday at a pretrial hearing for Gastineau in San Bernardino Superior Court that a motion to challenge the charges against his client was already on file with the court.
But Haynal also is requesting a new location for Gastineau's case via a motion for change of venue "due to pretrial publicity," he said in court.
Gastineau returns to court May 25 for a pretrial hearing. The court intends to address both motions at that time.
Gastineau, 31, of Redlands, is suspected of having a sexual relationship with a teenaged girl in the department's Explorer program at its Highland station. As the advisor to the program, he and the girl became close friends and attended Explorer functions.
At a preliminary hearing on Dec. 15, deputies testified about the girl's statement that she had sex with Gastineau about 20 times - six times before she was 16. Deputies said they also had videos of the girl and Gastineau allegedly having sex.
Detective Tyson Niles said at the hearing that Gastineau admitted to him that he had sex with the girl once in his apartment.
Haynal challenged the victim's statement to detectives at the preliminary hearing. He later said her story "stretches the bounds of credibility" and was "all over the board."
A week after the hearing, prosecutors charged an additional two counts each of committing a lewd act upon a child and of having unlawful intercourse. Gastinuea now faces a total of 10 felony counts.
