In Chicago, a man facing charges of arson and murder related to the tragic death of a local firefighter will remain in custody until his trial, as announced by the Cook County State’s Attorney’s Office on Monday.

Sheaves Slate, 27, made a court appearance on Monday after being unable to attend a scheduled hearing on Saturday due to hospitalization.

According to the prosecution, Slate allegedly took up residence unlawfully in a building located in the 1700 block of West North Shore Avenue and ignited a fire in the basement following a dispute with two occupants.

Tragically, while combating the flames, Chicago Fire Department firefighter Michael Altman fell when the first floor of the building gave way, plunging him into the basement on Monday.

The 32-year-old emergency medical technician with the CFD succumbed to his injuries the following day, on Tuesday.

Authorities apprehended Slate on Wednesday in the 800 block of West Irving Park Road.

After his court appearance Monday, Cook County State’s Attorney Eileen O’Neill Burke said in a statement:

“We are all grieving the tragic loss of Michael Altman – a young father and dedicated firefighter who followed in his family’s footsteps to serve and protect others. His death is a profound loss for the Chicago Fire Department, his family and loved ones, and communities across Cook County. My thoughts are with all who are mourning during this incredibly difficult time.

“Our felony review prosecutors acted swiftly, in collaboration with the Chicago Police Department, to approve charges including first-degree murder and aggravated arson in connection with Michael’s death. This marks the second time under my administration that murder charges have been brought for a firefighter’s on-duty death – a sobering reminder of the risks first responders face every day as they confront danger to keep us safe.

“We will pursue this case with the utmost seriousness and will seek justice in court on behalf of Michael, his family, and the people of Cook County.”

The ABC7 I-Team learned that Slate also has a history of drug and retail theft charges.

Officials in court on Saturday said Slate recently failed to appear for a hearing in connection with a retail theft case, and he was already on suspension in connection with another retail theft case.

Altman, a fourth-generation CFD firefighter, was a husband, and a father to a young child. His wife is pregnant with their second child.

Altman’s funeral is set for Friday at Saint Rita of Cascia at 10 a.m. The visitation is scheduled for Thursday, from 3 p.m. until 8 p.m., at the same location.

ABC7 will have live coverage of Altman’s funeral on our air and wherever you stream on Friday morning.

Slate is next due in court April 8.
