A 4-year-old girl fatally shot her 4-year-old cousin with a gun the children found underneath a bed in Detroit on Thursday, police told CBS Detroit.

“They were playing in a room inside the home; the female found a long gun underneath the bed and pointed it at the male 4-year-old and pulled the trigger,” Detroit Police spokesman Adam Madera told CBS.

Police have not yet announced any charges in what CBS described as an accidental shooting.
