KANSAS CITY, Kan. -- A massage may have led to the killing of a popular community college professor, sources said.

Richard Urdiales, 53, was found beaten to death on Sunday outside a house on North 55th Street.

Urdiales was an English professor at Blue River Metropolitan Community College in Independence, Mo., but he also made extra money as a masseur.

Students told KCTV5's Liana Joyce that Urdiales had a unique teaching style they could relate to. "He was really loud sometimes. And I liked it, because I'm really loud, too," said Lindsay Walker, a student at the school. She added, "He was one of my favorite teachers."

"It shocked me because I didn't feel that anybody could be mad at the guy," said BRMCC student Cory Bolin. "It just seems sad because he had a second job and somebody had the wrong impression that this had to happen."

Urdiales was giving a woman a massage inside the house when the woman's boyfriend showed up and attacked him, sources said.

Prosecutors charged the woman's boyfriend -- Daniel C. Hoyle, 21 -- with first-degree murder.

On Wednesday, Hoyle was being held in the Wyandotte County Jail on a $500,000 bond.
