(STMW) — A man suspected of killing his estranged wife and 5-year-old daughter inside a Little Village home before shooting himself early Tuesday has died, authorities said.

Officers discovered the family at the single-story home in the 2800 block of South Kildare Avenue about 12:15 a.m., finding 28-year-old Kelly Coca and her daughter, Karla Eguez, each with a gunshot wound to the head, authorities said. The 28-year-old husband and father was also found in the house with an apparent self-inflicted gunshot wound to the head, authorities said.

Juan Eguez was taken to Mount Sinai Hospital, where he was pronounced dead at 11:07 a.m. Wednesday, the Cook County Medical Examiner’s office said.

Neighbors reported hearing arguing coming from the home, shortly before hearing gunshots, a law enforcement source said.

Coca and her daughter had just returned to their home on Kildare after a trip to Miami, where her estranged husband lives, the source said. Karla had spent a month with her father, the source said.

Coca and her daughter were dead at the scene, according to the Chicago Fire Department.

In January 2011, Coca was the alleged victim of a domestic battery. The Florida man charged with the crime, allegedly performed a leg lock on her, dragged her from her room and began punching her head. He then allegedly bit her on the right hand, causing her to bleed.

The man, who records indicate was enlisted in the U.S. Army, was arrested and held in lieu of $10,000 bond. The charges were later dropped.

Coca worked as a hygiene specialist for Swisher Hygiene and had been with the company since October 2011, a company spokesman said.

A company van was parked across the street from her home Tuesday morning.

“We are incredibly saddened to hear about this tragic news,” the company said in a statement. “Our thoughts and prayers are with the family and all that have been affected by this senseless tragedy. Kelly was a model employee and she will surely be missed.”
