Watch: "Every parent's nightmare" - What we learned from the charges against D4vd

US singer D4vd has been accused of having "a significant amount" of images depicting child sex abuse on his phone and iCloud account when he was arrested over the death of a 14-year-old girl found in his car, prosecutors say.

The discovery was made through search warrants in the case as police investigated how Celeste Rivas Hernandez died and ended up in the singer's Tesla, prosecutors said in court on Thursday.

Prosecutors allege D4vd repeatedly sexually abused the teen before killing and dismembering her body, which they say he did to protect his lucrative music career.

D4vd, whose real name David Anthony Burke, has pleaded not guilty to murder and other charges in the case.
