Egypt's occasionally fragile sectarian ties have been shaken by the murder of a Muslim whose wife converted to Islam against her Christian family's wishes.
Police said Mariam Khilla's brother, Rami, broke into their Cairo home and opened fire, killing her husband and injuring Mrs Khilla and their daughter.
Mr Khilla had been searching for Mariam ever since she left home to marry Ahmed Saleh about two years ago, police said.
Muslim-Christian friction is unusual in Egypt but sometimes leads to violence.
