A killer choked his lover to death then texted the victim’s young son pretending to be her.
David Anderson strangled Louise O’Brien at their flat in Perth in April this year.
Louise, 36, was later discovered dead on a bed with a heart-shaped chocolate beside her.
Anderson is thought meantime to have used the mum’s phone to contact her 11 year-old son making it look like she was still alive.
He went on to carry out a web search trying to discover if murder accused are locked up.
The 41 year-old eventually confessed to his mother he had “done something terrible”.
The first offender faced a murder allegation as he appeared at the High Court in Glasgow on Friday.
But prosecutors instead accepted his guilty plea to the reduced charge of culpable homicide.
Anderson was remanded in custody pending sentencing next month.
