At a registered, closed Sigma Tau Gamma costume party at around 1:30 a.m. Oct. 28, a fight broke out between 8-15 people and a University of Arkansas student after he was asked to leave.

Almost three minutes after the first shove, UCAPD Officer Rodney Purvis stopped in front of the house while on patrol because he saw a possible fight. He got out of the car and pulled out his service pistol.

According to the report, Darrell Ray Dean, an 18-year-old University of Arkansas student, told police he was drunk on a public sidewalk and “said a few things he should not have and used some profanities toward the people getting hostile toward him.”

Dean told police he was attacked first, which is consistent with security footage from outside the Sig Tau house.

Witnesses told police they saw Dean pull out a knife.

Dean told police “he attempted to pull out his knife because he was being severely beaten by a large group of hostile people.”

After pulling out his spring-assisted pocket knife, Dean is seen in the footage being knocked to the ground, where men continue to kick him until Dean is helped up and then pinned against a silver truck, surrounded by a tight circle of people.

His friend, Tyler Stacey, 18, also a UofA student, is seen in the footage helping Dean away from the altercation until Purvis stops his car in front of the house.

Sig Tau President Lucas French can be seen running up to the police car’s driver-side window. According to the report, this is when Lucas told Purvis about a knife being pulled on them.

Purvis can be seen getting out, drawing his service pistol, aiming it at Stacey and commanding him to get down.

Stacey said via text he felt Purvis’ response was “not really reasonable given the fact a knife was never actually used and I only tried breaking up the fight.”

“The cop came out with his gun already aimed at me then told me to get down,” he said. “I was just pissed off because I never actually did anything wrong.”

Sgt. Michael Hopper, UCAPD’s public information officer, said, “Officer Purvis was operating on the only information he had, which was there had been some sort of altercation and at least one knife was involved, so he approached them as such. The pointing of a firearm is a use of force and the appropriate reports were completed.”

After members tell Purvis that Stacey is the wrong person, Purvis is seen putting his pistol back in the holster and approaching Dean, who, according to the report, “seemed disoriented and confused and began to walk toward Donaghey [Avenue.]”

According to Purvis’ review of the footage for the report, student and Sig Tau member Ryan Walker Akridge and Dean can be seen arguing until nonstudent Thatcher Strack is seen “inserting himself in the argument” before “shoving Dean and starting a fight between Dean and Strack.”

Officer Kaylob Boykin, who responded to a 911 call about the fight, said that when he reviewed the footage he saw someone push Dean, and then Dean pushed back before more people “started to tangle up.”

Boykin observed Dean opening the knife in the footage but wrote Dean “changed his mind” and swung. Purvis observed Dean opening the knife and placing it in a “reverse grip” while readying his hands.

After this, both officers wrote in the report that Sig Tau members and others involved in the fight kicked Dean after he was knocked to the ground.

Stacey said, “I was talking to some other buddies when we heard fighting,” he said. “I eventually saw [Dean] was involved, so I went over to try and de-escalate the situation and get out of there.”

“By the time I got there, six or seven of what looked like the frat members were kicking him while he was on the ground. At this point, he could not defend himself,” he said.

“I tried to figure out the situation and why he was getting beat up, but all I got was a lie from one of the members who said he had tried using the knife on them,” he said.

Akridge told police Dean punched a Sig Tau member first so the people around the altercation stepped in to stop him, despite footage showing Dean was shoved first.

According to the report, French told Purvis he witnessed Dean try to use the knife, and he told Boykin “that he caught Dean off guard by striking him in the side of the face, so he would drop the knife” before calling 911.

Sig Tau’s president French said, “Calling the police was the correct decision. I think it was handled properly.”

Purvis wrote in the report Strack “started a fight with Dean knowing that he and his friends completely outnumbered Dean,” and Dean had several scrapes and cuts from the fight.

Dean was charged with public intoxication, according to Arkansas CourtConnect.

Dean, Strack and Akridge did not respond to requests for comment.

Because Purvis saw “obviously intoxicated” members and “empty beer cans … laying around the front of the Sig Tau house,” Sig Tau was given an alcohol violation, in addition to a conduct violation for its members being involved in the fight with Dean.

French said, “Nothing has happened yet” regarding disciplinary action.

“Sig Tau was on probation but not suspended so we were allowed to host events,” French said.
