Calls from those phones led investigators to Lipatov, the alleged driver.
"I didn't see what happened there," Lipatov told them in a video released by police. "I just took Yuri there, waited for him and gave him a lift back."
When an interrogator asked Zarutsky about the crime, he allegedly said, "I don't want to talk about it."
Police concluded a "hostile relationship" stemming from Dmitrichenko's professional interaction with Filin was his motive.
Act 4 - A Moscow Court
The three men faced a judge Thursday, who ordered that they be kept in police custody until the investigation is over.
If convicted, the attackers could face up to eight years in jail for willfully inflicting damage on the health of another.
It may take at least six months for Filin to recover from the burns.
In the meantime, Galina Stepanenko, a former principal dancer, will run the company.
She says she's going to follow Filin's plans and she believes the dancers will now be united by greater respect and care for each other.
Doctors performed a skin graft on Filin and, after a second eye surgery, they were able to save his sight.
His colleagues are now working to ensure his artistic vision isn't lost.
