ROMEOVILLE, Ill. (WLS) — The suspect in the murder of a family of four in Romeoville is believed to be dead along with another person of interest after a police chase and shooting in Oklahoma Wednesday.

A GoFundMe Fundraiser created to help pay for the family’s funeral expenses.

Romeoville police said they do believe they know the motive behind the murder of a family of four, but will not release it yet.

Investigators said the man and woman lived in Streamwood, identifying the male suspect as 31-year-old Nathaniel Huey, Jr.

The woman was reported by family as missing from Streamwood Tuesday night, police said.

On Wednesday morning, Catoosa, Oklahoma officials were alerted to a vehicle in their jurisdiction that matched a description and license plate of the suspects’ vehicle.

During an attempted traffic stop, the vehicle drove away and crashed, police said.

The vehicle caught fire, and officers believed they heard two gunshots.

A woman was found in the passenger seat with a gunshot wound, police said. She was taken to a hospital in critical condition and later died, an attorney representing her family said.

An attorney representing the woman’s family identified her as Ermalinda Palomo. Neighbors said she and Huey lived in Streamwood together for about the past six years.

Huey was the owner of a security company and had extensive firearms training.

The two are being considered as persons of interest in the murder of a family of four, Alberto Rolon, his wife Zoraida and their two young sons.

“Evidence has shown us a nexus between the suspect and the victims as well as a possible motive,” Romeoville Deputy Police Chief Chris Burne said.

The victims were found on Sunday night when police conducted a well-being check.

Palomo’s family attorney said her family reported her missing after her phone was shut off following a series of concerning text messages.

“And, they thought that she sounded scared. But, they don’t have any direct information other than, ‘Take care of my grand babies,'” said attorney John Paul Ivec.

Ivec said he’s not aware of her involvement with the family in Romeoville.

According to internal investigative reports obtained by the ABC7 I-Team, police knew Huey was a suspect early on.

Shortly after the victims were found, police put out a statewide alert for Huey and the car he was driving – the same one authorities chased in Oklahoma Wednesday.

Romeoville murders: What we know after suspect, person of interest dead in Oklahoma

ROMEOVILLE, Ill. — New details have emerged after the man suspected of killing a family of four in Romeoville died in Oklahoma.

Nathaniel Huey Jr., of Streamwood, was suspected in the deaths of 38-year-old Alberto Rolon, 32-year-old Zoraida Bartolomei and their two sons, ages 7 and 9. A female with a relationship to Huey Jr. was also identified as a person of interest in connection to the shootings.

Attorney John Paul Ivec has identified the female person of interest as Ermalinda Palomo, a mother of five and grandmother of five. He went on to say that she had no criminal history and was a victim of a murder-suicide.

Palomo had been reported missing by her family after the attorney said she stopped texting them. The attorney said the Palomo family does not know what her relationship or connection to the four killed in Romeoville is.

Police in Catoosa, Oklahoma were alerted to the presence of Huey Jr.’s vehicle Wednesday morning in their jurisdiction, police said. The vehicle attempted to elude police and it was involved in a fiery single-car crash.

On Wednesday afternoon, police were seen investigating at a home in the 400 block of East Irving Park Road in Streamwood in connection with the incident. Neighbors in the area said the pair lived in the home and were shocked to hear about the investigation.

State records show Huey Jr. had a security business where he claimed to have a background in weapons.

Police said there’s a possible motive between Huey Jr. and the Romeoville family, but would not eleborate citing the investigation.
