A suspect was arrested in connection to the Hawthorne Hills apartment fire in Cedar Rapids, authorities announced on Saturday morning.

Dallas Tullis, 24, of Cedar Rapids, was charged with first-degree arson, assault on a police officer, assault causing injury, and interference with official acts.

Tullis had been hospitalized at Mercy Medical Center until Friday afternoon, where he was under a police hold. He was arrested immediately following his discharge from the hospital.

Cedar Rapids Police and fire investigators determined that Tullis allegedly set the fire at the 2-story apartment complex shortly before 8:30 a.m. on Thursday, February 28. He was initially taken into custody near the scene of the fire, but needed medical treatment and was taken to a hospital. There, he allegedly assaulted a police officer and a hospital security guard.

The fire at the apartment, 2255 C Street SW, injured five including a firefighter. A 65-year-old male suffered life-threatening injuries and is still hospitalized at the University of Iowa Hospitals and Clinics. Three adults, including Tullis, received non-life-threatening injuries.

16 residents were displaced by the fire, which caused significant damage to the building.

Tullis is being held at the Linn County Jail.
