Lisa Brown, 21, was convicted of murder Friday after a trial in High Court in Glasgow, The Scotsman reported. John Wilson, 25, was found guilty of culpable homicide.
Prosecutors said Brown was angry because her mother, Anne Brown, 51, would not let her see her 20-month-old son. Anne Brown was battered with a steel flashlight at her home in Burnhouse, Ayrshire. Her body was wrapped in a sleeping bag and dumped.
The body was discovered Oct. 24 after Anne Brown's mother reported her missing.
Lisa Brown was pregnant at the time and has since had the baby. In one of several e-mails she sent to friends and ex-boyfriends, she complained her mother was unwilling to be her birth partner for the delivery.
"We will miss her terribly and feel no sentence can be adequate to compensate us for her loss," Anne Brown's brother, Michael Elliot, said after the verdict. 'We would also add that we feel it is reprehensible that neither of the accused in this tragic case has expressed any remorse for their part in this heinous crime."
