CHICAGO (WGN) — Charges have been dropped against a woman and her 14-year-old son following a fatal shooting at a Chicago hot dog stand earlier this month.

The woman and her son had been charged after authorities accused her of instructing the teenager to shoot a man that had allegedly punched her in the head multiple times.

The State Attorney’s Office confirmed Monday that, in light of emerging evidence, those charges have been dismissed.

According to police, the pair were arrested Wednesday after being identified as the individuals who were involved in the fatal shooting of a 32-year-old man at Maxwell Street Express on South Halsted Street just after 11 p.m. on June 18.

Court documents alleged the woman entered Maxwell Street Express to get food while her son waited in the car outside.

Shortly after, a 32-year-old man entered the restaurant an argument ensued between him and the woman, court documents state. She was allegedly texting her son from the store, signaling him. He entered the restaurant during the argument.

The argument quickly turned physical when the man punched the woman in the head multiple times, authorities allege. Then, the documents state, the woman’s son displayed a firearm and fired shots at the man. He sustained a gunshot wound to the back.

Documents state there was a witness laughing and encouraging the incident. The man then fled the restaurant, and the 14-year-old allegedly followed him, firing more shots.

The man sustained two more gunshot wounds to the back and was pronounced dead shortly after.

Authorities alleged there was a struggle between the boy and his mother over the gun before they got into their vehicle and left the scene.

The pair turned themselves in and were arrested on Wednesday. Neither has a reported criminal background.

The Attorney’s Office said that based on the evidence, prosecutors would be unable to meet the burden of proof in the cases. Additional information was not released.
