Detectives investigating Jamarion's death discovered he was blind and had limited mobility, requiring the use of braces on his legs.

The police association said: "Jamarion had no way to defend himself against the suspect’s attack."

Dallas was charged on November 19 and is also accused of unlawful possession of a firearm.

The police association has set up a fundraising page following Jamarion's tragic death to help his mum.

The GoFundMe page reads: "Jamarion’s death has left an impact on the members of the St. Louis County Police Department and we feel compelled to do more, especially at a time of year when families typically gather and celebrate the holidays.

"We feel for Aunyae at this incredibly difficult time where she has to bring a baby home from the hospital, while planning her son’s funeral and also trying to care for Micaiah who was in the apartment when this horrible act occurred – all with extremely limited resources.

"With the permission of the family, we started this fundraiser to raise money for Jamarion’s funeral expenses, provide essential care products for the baby and give Micaiah a Christmas she will not soon forget.

"The St. Louis County Police Association is the first to donate, but we pray we will not be the last. Please donate whatever is possible to support Jamarion and his family."

As of Monday, the GoFundMe page has raised $32,076 of its $35,000 (£27,000) target.
