Bo Gu
Following the Wang Lijun incident and Bo's removal from key Communist Party posts, Gu was placed under investigation for Heywood's death. On 10 April 2012, Gu was detained and "transferred to the judicial authorities" as part of the investigation. In an unusual move, state media appended her husband's surname in front of her own (rendering her name as Bo Gu Kailai), extremely unusual for married women in People's Republic of China, without any explanation. Some speculate that it may imply that Gu may have acquired citizenship of a foreign country, and as a result "Bo Gu Kailai" appeared on her official documents; Others suggest that this is because authorities wanted to emphasize that Gu's alleged crimes were linked to misconduct by her husband.
