Dalrymple allegedly entered the unguarded door, which was reportedly accessible only by keycard (which Dalrymple had). The door led to a nook that was separated from the dressing room by a partial wall. According an attorney's letter obtained by ESPN as well as multiple sources, the women heard the door open and shouted "We're in here!" They reportedly assumed it was a security guard and thought he'd left.

Several minutes later, one of the cheerleaders noticed a man's hand and a black cellphone pointed in their direction, according to several sources. At the time, the women were going "from fully clothed to completely unclothed," a cheerleader later told a Cowboys HR official and the team's general counsel, Jason Cohen. The cheerleader who saw the cellphone was certain the man was lurking and taking photos or video of them, according to multiple sources.
That woman ran toward him, shouting, "Hey, what are you doing?" The cheerleader, a veteran of several years on the team, immediately recognized Dalrymple, who she said dashed away, according to the letter. The other women did not see the man, according to the letter.
According to ESPN, the four cheerleaders immediately reported the incident to a security guard, who wanted to report it to the police, as Dalrymple's alleged actions would be a misdemeanor and a felony if proved. The police were not called, however, and the cheerleaders eventually made it to the luncheon. Afterward they reportedly met with Kelli Finglass, the cheerleaders' director, and all four reportedly wanted the incident to be investigated.
