While Ngo was still in the residence, the homeowner was able to escape from the locked room and ran to a neighbor's house. The neighbor immediately dialed 9-1-1 and Burbank police were dispatched to the residence. Police swiftly surrounded the house and the South Suburban Emergency Response Team (SSERT) was activated.
Believing the gunman was barricaded in the home, SSERT units took up positions encircling the dwelling. Recognizing the home directly across the street offered the most favorable vantage point, SSERT officers obtained permission from the homeowner to use the residence as a command post and sniper position. SSERT resources on the scene included personnel from Bedford Park, Bridgeview, Chicago Heights, Country Club Hills, and Oak Lawn along with officers from several other south suburban agencies. Specialized equipment on hand included two armored vehicles and a helicopter.
Deeming the situation as a potential danger to nearby persons, police evacuated approximately a one block radius while local schools were placed on lockdown.
The standoff lasted well into the afternoon. About 3:00 p.m., police detonated smoke grenades to use as cover while units battered in the front door. A phone box was inserted into the home and negotiators used a public address system to urged the gunman to establish communications with law enforcement. Getting no response from the perpetrator, police made entry into the residence about 5:00 p.m. only to discover that the gunman had fled sometime prior to their arrival.
Burbank detectives quickly linked the gunman with another home invasion which occurred in Orland Park a month earlier. In the Orland Park incident, Ngo broke into a home by gaining access through a basement window. Once inside, Ngo found an 11 year-old boy home alone. Ngo locked the boy in a bathroom and took money, jewelry, computers, and a safe before fleeing. A neighbor's security camera captured photos of Ngo and the 11 year-old was able to identify him from a photo lineup.
The subsequent investigation by Burbank and Orland Park detectives pinpointed Ngo as a suspect in a series of robberies that targeted Vietnamese nail salon owners. Ngo was also suspected of crimes in Chicago, Skokie, and Waukesha, WI. Police were able to track Ngo to a home in Yorkville, IL. On August 12, 2008, Burbank, Orland Park, and Yorkville police apprehended Ngo near his home.
In February 2011, Ngo was found guilty of the Burbank home invasion after a jury trial at the Bridgeview Courthouse. He was sentenced to 40 years in prison for the crimes of Home Invasion, Illegal Discharge of a Firearm, and Aggravated Kidnapping. He stood trial in July of 2012 and was found guilty of Aggravated Kidnapping and Residential Burglary in the Orland Park case. Ngo is currently incarcerated in Stateville Correctional Center, a maximum security prison in Crest Hill, IL. His projected parole date is June 18, 2081.
