CHICAGO -- A Chicago man stabbed his mother to death then doused her body in chemicals after she refused to buy him tickets to an Avril Lavigne concert, a jury found.
Robert Lyons, 39, was found guilty of first-degree murder Wednesday after a weeklong trial, the Chicago Tribune reported.
Prosecutors said that Lyons began to argue with his mother, Linda Bolek, when she refused to call a friend to arrange tickets for the concert in 2008.
Lyons stabbed his mother nine times in the back, then poured insecticide and drain cleaner on her body, prosecutors said.
A jury deliberated for just two hours before returning their verdict, the report said.
