This is reported by TASS about the link to the united press service of the city courts.
It is noted that she was arrested for two months.
"The Smolninsky District Court issued a decision on the selection of a preventive measure for Marina Kohal ... The court granted the request of the investigation," the statement said.
The investigation noted that Kohal must be sent to a pre-trial detention center, since the crime is especially grave and she does not have permanent registration in St. Petersburg.
The prosecution also pointed out that a woman can put pressure on witnesses, even though their circle has not yet been determined.
Earlier it was reported that Kohal was detained in St. Petersburg on suspicion of the murder of her husband. On July 30, the dismembered body of the musician was found in an apartment on Nevsky Prospekt, where he lived with his wife and child.
Alexander Ziganshin, a friend of rapper Andy Cartwright, commented on the musician's death in an interview with the 360 TV channel.
