Li Yi
Li Yi agreed, and, in spring 627, Li Yi pretended to receive a secret order from Emperor Taizong to return to Chang'an from his then-defense post at Yi Prefecture (宜州, in modern Tongchuan, Shaanxi). He seized Zhao Cihao (趙慈皓) the secretary general of Bin Prefecture (豳州, in modern Xianyang, Shaanxi) and occupied Bin. Emperor Taizong sent his brother-in-law Zhangsun Wuji against Li Yi, but even before Zhangsun's arrival, Zhao's associate Yang Ji (楊岌) attacked Li Yi, whose forces collapsed. Li Yi tried to flee to Eastern Tujue, but when he arrived at Wushi (烏氏, in modern Pingliang), his associates assassinated him and cut off his head to be delivered to Chang'an. Emperor Taizong had his head hung in the streets and changed his name back to Luo, excising him from the imperial clan rolls. His wife Princess Meng, Li Wujie, and his brother Luo Shou (羅壽) were all executed.
