MMA fighter Aaron Rajman died Monday night at the age of 25 after being shot inside his home in West Boca Raton, Florida.

According to Wayne K. Roustan and Adam Sacasa of the Sun-Sentinel, the Palm Beach County Sheriff's Office said multiple men entered Rajman's home before fatally shooting him and driving away.

Per Roustan and Sacasa, fight promoter Dave Zalewski commented on the death of his friend: "I'm just literally at a loss for words. Everyone I talked to is sickened. He was the most humble guy around, he never talked bad about people."

Sherdog lists Rajman as a featherweight who boasted a 2-2 career record as a professional.

He last competed in May 2016, losing to Luis Raul Gomez Alvarez by knockout at House of Fame 5: Resurrection Day in Hallandale Beach, Florida.

Police said there is currently no known motive for the shooting, and there are no suspects.
