RICHARDSON - Police are investigating whether a Richardson high school coach arrested on charges of having sex with two female students had other improper relationships as well.
According to a police affidavit, Brent M. Archie, 31, engaged in sexual intercourse more than 10 times in his office at Richardson High and had oral sex more than 30 times in his Plano home, all with the same student, who is now 17. She was 15 when their relationship began in May 2007 and continued until his arrest Wednesday, according to the affidavit.
In addition, he is accused of having sexual intercourse and oral sex with a 16-year-old Richardson High student between February and March of this year at his Plano home and in a vehicle in Richardson, according to police.
Archie now faces four counts of having an improper relationship between an educator and student, and police are trying to determine if he was improperly involved with any other students.
He served as head wrestling coach and an assistant football coach at Richardson High School last year. He was slated to coach at Berkner High School this fall and teach history at Liberty Junior High, said Tim Clark, a district spokesman.
Archie has been was placed on paid leave by the school district pending the outcome of the case.
School officials are expected to discuss the case this afternoon at a district news conference.
Sgt. Kevin Perlich of the Richardson police department said that at first Archie denied the initial allegations, from the girl who is now 16.
But, "after talking to him and [his] taking a polygraph, which he failed, he made a confession," Sgt. Perlich said.
Archie refused to discuss the allegations regarding the older girl, invoking his right to an attorney, according to an affidavit
Police began investigating the initial allegations July 19 after a counselor at a Colorado camp alerted Richardson police, according to an affidavit.
The counselor told authorities she learned about the relationship when questioning the girl about an argument she had with her 16-year-old boyfriend.
The girl said she couldn't break up with him because her " boyfriend knew her secret," according to an affidavit.
The girl told the counselor that she initiated the relationship with Archie and eventually ended it, an affidavit states.
Police became aware of the second girl during that investigation, and after speaking with police, the girl admitted to the relationship.
Richardson police have not identified either victim or indicate how they knew the coach.
When reached by phone Thursday, Archie's mother said she was in shock from the news.
"We don't want to talk right now," Sheila Archie said. "I can't even talk. It's been a horrible day.
Clark said Thursday that he believes this is the first case of its kind in the district's history.
Archie has worked for Richardson ISD for seven years. In addition to coaching, he has taught world history and an elective course that focuses on college-readiness skills at Richardson High School, according to the school's Web site.
Archie remained in the Richardson jail Friday in lieu of $40,000 bond for each charge. If convicted, he faces two to 20 years in prison and a fine of up to $10,000 on each count.
