The wailing of his girlfriend’s inconsolable infant daughter “aggravated” a Lockport teen to the point where he picked up the baby and shook her at least 10 times, according to court documents.

Jon Karlson, 17, is being held in the Will County Jail on $2 million bail. He faces charges that he murdered 2-month-old Aaliyah J. Gedminas, who died from head trauma and bleeding on her brain in December.

Karlson appeared in court Wednesday for arraignment, where his next court date was scheduled for Feb. 1.

A search warrant filed in court last month by a sheriff’s detective investigating the case includes some detail of the detective’s interview with Karlson.

In the warrant, which sought a cell phone as well as computers and discs or drives, Detective Brian O’Leary states that Karlson told him he was watching the baby alone on Dec. 6.

The baby began to cry in her crib, and Karlson allegedly told the officer he started to get “aggravated” because he could not quiet the girl. He told O’Leary that he picked the baby up, his hands under her arm pits, and shook her 10 to 15 times, the document said.

She stopped crying, and he laid her down in her crib. About 15 minutes later, he noticed on a baby monitor that she was moving her arms, the document said. He checked on her and found the baby pale and limp.

Karlson called the girl’s mother, who was at work, and said Aaliyah “did not look right,” so she left work and came home to take her to the hospital, authorities said.

Shortly after 7 p.m., Karlson and the baby were in the back seat while the mother was driving near Bruce and Gougar roads when Aaliyah stopped breathing and the couple called 911, authorities said.

A Lockport Township Fire District ambulance arrived at the intersection, and firefighters performed CPR and rushed the girl to Silver Cross Hospital in New Lenox.

She then was transferred to Lurie Children’s Hospital in Chicago, where she died Dec. 7.

Karlson was arrested the day the baby died. He was initially charged with aggravated battery of a child, but the charge was upgraded to murder after the infant died.
