A Minneapolis family torn apart by a domestic murder a decade ago suffered another violent tragedy this week when a 5-week-old boy was killed in what police say was a severe case of child abuse.

The family's latest heartbreak involves the death of Delijahjuan Winden. The infant wasn't breathing when officers responded to an emergency call early Tuesday to an apartment in North Minneapolis, police said.

An autopsy concluded Delijahjuan died from "blunt force head injuries." The Hennepin County medical examiner's office ruled the death a homicide.

Daniel Leikas, 25, described by police as the boy's caregiver, was charged today with second-degree murder. A criminal complaint accuses Leikas of growing increasingly frustrated with the baby, who had been crying and fussing much of the night. The complaint states Leikas told police held the boy over his head and slammed him into a car seat.

The case is the second time the baby's mother, Zonebia Benson-Winden, 20, has dealt with murder in the family. A decade ago, Benson-Winden's mother, Shannon Haiden, pleaded guilty to killing Haiden's stepfather.

In April 1997, Warren Winden, 50, was found shot and stabbed to death in his home in the 4300 block of Aldrich Avenue South. The slaying, initially thought to be a random robbery, shocked an affluent neighborhood unaccustomed to such violence.

Police later concluded the murder was a family affair. Investigators found Haiden's fingerprint on the molding of a window near the front porch. Officers spoke with Haiden and learned that she had threatened her stepfather.

Haiden later gave a statement in which she said she went into the house at her boyfriend's urging in order to kill Warren Winden. Using her boyfriend's pistol, she shot her stepfather several times and then, after discovering him still breathing, cut his throat with a machete, a criminal complaint said. She ransacked an upstairs bedroom to make the crime look like a robbery and later gave the gun and knife to her boyfriend to bury, according to the complaint.

Haiden later pleaded guilty to second-degree intentional murder and was sentenced to 22 years in prison. State prison records show Haiden is serving time at a Shakopee prison.

This week's homicide case unfolded when police responded about 6:30 a.m. to a call at an apartment building at 1240 Thomas Ave. N. The boy's mother and Leikas were in the apartment when police arrived and found the baby not breathing.

Lt. Amelia Huffman, police spokeswoman, said Leikas appears to be the "male parent figure of the home," but did not know if he is the baby's biological father.

Benson-Winden did not return a call seeking comment. Her grandmother, Mary Winden, declined to comment Wednesday.

Leikas has a lengthy record of arrests. He has been arrested multiple times for damaging property, theft and carrying weapons. He has also been convicted for failing to register as a predatory offender.
