Investigators believe the killer used the blood of the victims to write the message, The Moscow Times
reports. The message was written in English.
One investigator has told The Associated Press
said the killer might be trying to mislead police by drawing attention to the all-girl punk rock protestors.
The killer "was trying to avoid suspicion by misleading police," investigator Andrey Sheptitsky warned.
Three members of the band were sentenced
to two years in prison August 17 for performing an anti-Putin "punk prayer" inside a Russian Orthodox cathedral back in February.

Pozlov suggested the words "Free Pussy Riot" may have been a "dirty provocation" to discredit the band.
"I am sorry that some freaks are using Pussy Riots band name," he said in defense of his clients and their supporters.

The killer could have been a Pussy Riot supporter, but according to investigator Andrey Sheptitsky, it looks like the women were murdered in a robbery. Sheptitsky said the apartment was a "total mess."
Sheptitsky's theory is just that, however. No motive for the killings has been confirmed, and according to BBC News
, investigators have found no immediate link between the murders and the band.
Earlier this week, two members of Pussy Riot fled Russia to "protect themselves," CNN
reports. It is unclear if these two women were involved in February's protests, but with all the hatred and backlash against the band, they just wanted to go somewhere where they could feel safe.
