Two Montgomery County high school students have been charged as adults in a vicious gang-related beating of a 15-year-old boy outside a restaurant in Olney, according to documents filed in court Monday and last week.

The victim in the March 27 attack, which was caught on cellphone video, suffered cheekbone fractures, was knocked unconscious and was left with a severe concussion. “He’s doing better. He’s out of the hospital,” his father, a physician, said Monday, adding that it was unclear whether his son would suffer long-term effects from the concussion. “Who knows? We’re just crossing our fingers he gets better quickly.”

The suspects attended Sherwood High School and belonged to a group of teenagers who call themselves the Freaky Too Gang, authorities said. One of the boys outranked the other in the gang, and encouraged him to attack the victim, according to court records. Several days later, inside Sherwood’s cafeteria, both teens allegedly approached another student who had recorded the beating, cornered him and allegedly told him not say anything.

“Watch your mouth, watch yourself,” one of the suspects said, adding, “You want me to clock you right now in the hallway? I’ll get security and watch me body-bag you.”

The documents identify the suspects as Christion Moody, 17, and Thomas D. Kozlowski, 16. Both have been charged with counts related to first-degree assault, witness intimidation and telephone misuse.

The court records do not say whether either teen is represented by an attorney. Neither the suspects nor their parents could be immediately reached for comment. It is unclear whether the students still attend Sherwood. School officials are on spring break and could provide only limited comment.

“We are cooperating with the police,” said Dana Tofig, a school system spokesman.

It also wasn’t clear how many teens are part of Freaky Too. Capt. Paul Starks, a Montgomery police spokesman, said investigators do not think the group is engaged in other criminal activity. Still, on the night of March 27, he notes, at least some of the youths appear to have come together for the purpose of assaulting another teenager. “Just because they may not be a bona fide gang doesn’t detract from the seriousness of the assault and later intimidation,” Starks said.

According to court records, events preceding the assault outside Panera Bread date back about one month, when Moody began sending pictures — online via Snapchat — to the victim’s 14-year-old girlfriend. The victim, who attends the private Our Lady of Good Counsel High School, told Moody to stop, according to police and the victim’s father. Moody and Kozlowski then called the victim three times, police allege, and told him to quit disrespecting them.

“I’m coming after you,” Moody said, according to arrest records. “Keep your eyes open. You’re not safe.”

“Better keep your head up,” Kozlowski added, according to the arrest records.

Although he is identified in court papers, the injured student is not being named by The Washington Post because he is a juvenile and because he appears to be the victim of a violent crime. His father spoke on the condition that he not be named.

On March 27, the victim was at Panera near Routes 108 and 97, when he noticed friends of Moody’s and Kozlowski’s inside. He tried to leave the area, but was eventually confronted by 15 to 20 people, including Moody, according to police.

The victim “had his hands in his pocket and did not want to fight,” detectives wrote. “Kozlowski then came from the side of [the victim] and struck him in the face. [The victim] did not see Kozlowski before he hit him. This caused [the victim] to lose consciousness and fall to the ground. Kozlowski continued to strike [the victim] multiple times in the face and head.”

The victim’s father said that after the assault, his son spent the night at a friend’s house and went to a hospital the next day.

Detectives charged Kozlowski as an adult. He was booked into jail and released on a $25,000 bond, according to court records. The records indicate that he must abide by a curfew.

Moody told police that Kozlowski was a subordinate in Freaky Too, according to court papers. Detectives allege that Moody “arranged for the group to surround [the victim] and told them to turn on their flashlights so that the assault could occur,” according to court records.

Police originally charged Moody as a juvenile and released him to the custody of his mother. Police then arrested him on Saturday, according to court records, this time charging him as an adult. Moody posted a $10,000 bond and was released, according to the records and a jail official.

Another parent whose son witnessed the assault said she fears for his safety. She said many students have seen a video of the incident. “The psychology of it has affected these students,” she said.
