15-year-old and 19-year-old shot attempting to steal XBox from online sale meetup

UPDATE: There is additional information in this case. We have it here.

CHICAGO - An attempted armed robbery left a 15-year-old in critical condition after being shot in the head and a 19-year-old shot in the shoulder after the pair tried to rob a 29-year-old man of a gaming console they'd arranged to meet to purchase in an online sale, authorities said.

A 29-year-old male was contacted by a 15-year-old male and a 19-year-old male in regards to purchasing the gaming console the man had posted for sale online (unconfirmed reports said it was an XBOX). The three males agreed to meet for the purchase of the listed item in the 3600 block of N. Octavia near the intersection of Octavia and Waveland in the Dunning neighborhood on the city's northwest side.

After initial contact between the three men a little after 10:00 p.m., one of the younger males pretending to purchase the item grabbed the gaming console and began to walk towards their vehicle without paying the 29-year-old for his item.

The 29-year-old ran after the younger male until he saw the second younger male sitting in the vehicle and pointing a gun at him.

The 29-year-old drew his own firearm and fired. The 19-year-old was struck in the shoulder and the 15-year-old sustained a gun shot wound to the head.

The 29-year-old male told police he only fired one shot.

Update: Earlier our report indicated the offenders were transported to Community First Hospital, however, it is believed the two offenders self-transported to Community First Hospital. Once there, they were taken into custody. The younger of the two offenders was transferred to Lurie Children's Hospital and the older offender was transferred to Illinois Masonic.

The 15-year-old who suffered the gunshot wound to the head was listed in critical condition and the 19-year-old was listed in fair condition.

There is no additional information whether or not the 29-year-old has a valid Illinois FOID Card or Concealed Carry License.

Area Five detectives are investigating. We'll continue to update this post as we know more.
