Slain girl found in shared grave

After finding the body of 4-year-old Sun Ji'er along with the remains of three others in a communal grave under an overpass in Xiangshui county, Jiangsu province, police on Wednesday arrested Sun Hailang, the boyfriend of the girl's mother, for his alleged involvement in her death.

Belongings of the dead kid.

All of the bodies were discovered on Tuesday when Sun Rongrong, the girl's father, traveled with police to the underpass to search for her after learning from his ex-wife of their daughter's death.

Police confirmed on Wednesday that the deaths of the other three infants involved no foul play.

An autopsy showed that Sun Ji'er's death was caused by blunt force trauma, and Sun Hailang was suspected of being involved.

Sun Rongrong, a native of Yancheng, divorced Wu Weiwei and left behind their 4-year-old girl. The woman then moved in with Sun Hailang in Xiangshui.

On Jan 27, the father asked to see his daughter but was shocked to learn from his ex-wife that the girl had died on Jan 21. Believing that the girl did not die of natural causes, the father alerted the police on Jan 29. With the help of police, Sun Rongrong located and exhumed the body of the girl along with three other unidentified bodies of infants.
