Three young girls were murdered in similar circumstances.

Lily Peters

The ten-year old girl had gone to spend time at her aunt’s house, which was not far from her own home; she took her bike.  Her cousin was to walk her home, and something went very wrong on that trip.  It is not clear to me whether the aunt was her mother’s sister, or her father’s.

Bianca Devins

She was in, apparently, a platonic relationship with a boy who was unsatisfied with just that.  They went to a concert, and on the return trip, he killed her.  He had propped up his phone on the dashboard in such a position as to be able to livestream the whole event, and published “stills” online.  He had also pre-set his phone to be playing a certain song on loop when the police would arrive.
