Cedar Rapids Police have arrested a 24-year-old man after they say he shot a woman, Monday evening.

Authorities took Zackary Dillon Ildefonso into custody Friday afternoon. He’s facing a charge of first-degree murder. Officers said in a news release he shot Heidi Lou Alberta Stephens, 33, Cedar Rapids, fatally wounding her.

November 20, police received a report of shots fired in the 1500 block of 2nd Avenue SE at 6:21 p.m. When officers arrived, they found a female victim on the ground in the property’s front yard.

“The victim had sustained a gunshot wound and police officers, along with firefighters and Area Ambulance Service personnel, began emergency medical treatment on the victim,” said the news release. “The victim was transported to UnityPoint Health-St. Luke’s Hospital.”

Heidi Stephens was declared brain dead at 11:10 a.m. on Wednesday. She was placed on life support and awaited organ donation.

“The subsequent investigation identified a suspect in the shooting as Zackary Dillon Ildefonso,” said the release. “Ildefonso was located this afternoon at 4:51 p.m. at 2925 Johnson Avenue NW, and arrested without incident for Murder - 1st Degree, Going Armed with Intent, Intimidation with a Weapon Causing Injury, Carrying Weapons, Felon in Possession of a Firearm, Trafficking Stolen Weapons, Burglary - 2nd Degree, and Possession of Stolen Property.”

Authorities said the burglary and possession of stolen property charges “stem from a separate case.”

Law enforcement didn’t say much about the circumstances that led to the shooting, only that they are part of the “ongoing investigation.”

Ildefonso is being held in the Linn County Jail.
