St. Charles police located the homicide suspect at QuikTrip after employees of the store called police when a man covered in blood entered the building's restrooms. The suspect is related the investigation of four people found dead inside a St. Charles home. 

Police were called to the scene of an active shooting in the 100 block of Whetstone at 11:55 p.m. Friday.

Lt. Wilkinson of the St. Charles Police Department said the 911 dispatcher heard gunshots and sounds of people screaming during the call. 

Upon arrival, officers said they saw Emery exit the home and get into a white Chevrolet Silverado in the driveway before leaving the subdivision. 

After attempting a traffic stop, police said the 46-year-old refused to get out the car and allegedly fired shots at the responding officers. 

"The officer had his firearm up, pointed at the suspect, giving him verbal commands to surrender," said Wilkinson. "He took gunfire from the suspect, the officer returned fire and retreated to the back of his vehicle to get better cover from the rounds that were coming towards him."

The officer, who has 16 years of experience on the St. Charles Police Force, and his K-9 unit were uninjured but Emery escaped on foot into a wooded area. 

St. Charles police confirmed that three people were shot and killed at the home on Whetstone and a fourth victim later died at the hospital from gunshot wounds sustained at the home. 

Zoe J. Kasten, 8, Jonathan Kasten, 10, Jane Moeckel, 61, and Kate Kasten, 39, have been identified by police as the victims. Jane Moeckel was known by her friends as Jane Campbell.

Police said Kasten was the mother of the two children found dead inside the home. 

During a press conference, officials said they believed Emery lived in the home and was Kasten's boyfriend.

The Major Case Squad was called in to assist with the investigation. Helicopter and SWAT teams were also called to assist in the search for the suspect.

Kate Katsen, 39, and her children Zoe and Johnathon were among the victims killed inside a St. Charles home late Saturday night. The photos provided of the family are from a few years prior. 

Hours later, detectives say Emery attempted to carjack a woman on DelaCroix near Muegge Road. He was unable to start the woman's car and then stabbed the woman seven times. Her injuries were non-life threatening, according to police.  

Police took Emery in custody around 7:30 a.m. when they found him at QuikTrip on 1st Capital Drive, just off Interstate 70. Workers at the convenience store called police when Emery, covered in blood, went into the bathroom. The 46-year-old sustained two gunshot wounds. 

Neighbors were shocked by the string of crimes caused by one man overnight.

"About midnight, we heard what sounded like automatic rifle gunfire. There was two bursts of about four shots each," said neighbor Mike Thelen. "So we got up and within minutes there were lights at the end of our street."

Thelen lives near the corner of East Cheshire and Muegee where St. Charles Police ended up in a shootout with the quadruple homicide suspect. Many neighborhoods surrounding Muegge Road were on lockdown during the seven-hour manhunt. 

Emery was hospitalized and treated for his injuries. 

St. Charles County Prosecuting Attorney Tim Lohmar said each of Emery's charges carries a possible penalty of 30 years to life in prison. 

"It's premature for us to make any sort of pronouncement about that right now, but I can tell you this thing looks and smells like a death penalty case," he said.
