Police continue to investigate whether a Richardson High School coach who is accused of having sex with two female students may have had other improper relationships, authorities said. Brent M. Archie, 31, remained in the Richardson jail on four charges Friday evening after two teenagers told police that they had sexual relationships with him. One of the girls said they had sex more than 10 times in Mr. Archie's athletic office at Richardson High School, according to an affidavit.
Richardson Police Chief Larry Zacharias said Friday that authorities are trying to interview a third student who may have been a witness or a victim.
Another Richardson High School coach who lived with Mr. Archie at the time of the alleged incidents has also been interviewed. Police did not identify the coach and said he had not been charged.
"We intend to do a lot more work," Chief Zacharias said. "There is still a lot we don't know. We won't stop until we're satisfied." Richardson school Superintendent David Simmons called the charges "disturbing and tragic" and encouraged staff and students who have additional information to contact authorities.
"It is not reflective of the behavior we require of our employees," Dr. Simmons said Friday during a news conference.
Mr. Archie has worked for Richardson ISD for seven years, including six years at Richardson High School. He was the school's head wrestling coach and an assistant football coach last school year.
In addition to coaching, he also taught world history and an elective course focusing on college-readiness skills.
Dr. Simmons said Friday that one of the alleged victims was a student in one of Mr. Archie's classes.
According to police, a 16-year-old said she had sexual intercourse and oral sex with Mr. Archie between February and March of this year at his Plano home and in a vehicle in Richardson.
She did not have sex with him on Richardson school district property, police said.
As police investigated her allegations this week, the first student provided the name of a 17-year-old girl who told police that she began having a relationship with Mr. Archie in May 2007 when she was 15, Chief Zacharias said.
That relationship allegedly continued until Mr. Archie's arrest Wednesday.
The second student told police that they had sex in his school office and engaged in oral sex more than 30 times in his Plano home, according to an affidavit.
Both girls initiated the relationships with Mr. Archie, Chief Zacharias said.
Mr. Archie was slated to coach at Berkner High School and teach history at Liberty Junior High this fall, but he has been placed on leave pending the outcome of the case.
He faces four charges of having an improper relationship between an educator and student. If convicted, he faces two to 20 years in prison and a fine of up to $10,000 on each count.
