Szendrei was attacked in broad daylight in a Delta park in September 2010. The man, whose name cannot be released, was just 17 years old when he picked Szendrei at random and killed her by beating her with a metal pipe.
On Wednesday, he stood up in court and addressed the Szendrei family, saying he was depressed, isolated and pathetic.
He apologized to the family, saying their pain must be unbearable, and acknowledging the agony he had caused.
“On that horrible day I took her life, I destroyed the Szendrei family,” he said.
At one point he apologized to "those women" — a possible reference to three other women he confessed to attacking near Burns Bog before he killed Szendrei.
“I robbed the community of sense of safety,” adding he feels he has ruined his family as well.
“My parents live in exile because of me,” he said, “I'm not going to ask for forgiveness because I don't deserve it.”
"No you don't,” said Szendrei's mother, Rachel, from the court’s gallery.
Szendrei’s father, observed to be in an agitated state all day, stormed out of the courtroom several times during and finally left to be checked out a nearby hospital.
The sentencing hearing, which continues all week, will determine whether the man, now 21 years old, should be sentenced as an adult.
