Working with Fontana police officials, Los Angeles County Sheriff’s investigators arrested three Los Angeles men ages 18 and 19 they say are connected to a “knock-knock” residential burglary ring targeting homes along the 210 Freeway from San Bernardino County to the San Gabriel Valley, officials said.

Davante Dean, 19, Kamron Brown and Darion Turner, both 18, and all from Los Angeles, were arrested Feb. 21 after investigators say the trio had just broken into a home in the the 6000 block of Firestone Drive in Fontana, officials said in a sheriff’s statement.

Members of the sheriffs Major Crimes Bureau’s Burglary-Robbery Task Force began looking into the possible link between Dean and a burglary ring after Dean’s arrest in February on suspicion of residential burglary in Pasadena, officials said.

Investigators believed Dean and others were targeting homes along the 210 Freeway corridor and in San Gabriel Valley neighborhoods, according to a press release.

While following Dean as he drove on the 210 Freeway into Fontana, detectives noticed two other people in the vehicle later identified as Turner and Brown, officials said.

Detectives watched as the three men came running out of the back yard of a home on Firestone Drive “carrying pillow cases” then drove off, the statement said.

With help from Fontana police, law enforcement officials pulled over the vehicle near Wilshire Drive and Magnolia Way near the Sierra Lakes Golf Club and found stolen items valued at several thousand dollars inside, the statement said.

All three were subsequently arrested and charged with burglary. Dean and Brown were arraigned and pleaded not guilty. Turner posted bail and was released from jail Feb. 23. His arraignment date has not been set, according to court records.

The LASD Major Crimes Bureau’s Burglary-Robbery Task Force (BRTF) investigators believed this crew is responsible for several other residential burglaries along the 210 Freeway corridor and within the San Gabriel Valley and Foothill areas. Detectives are collaborating with local investigators from several agencies and stations as this case continues to develop.

Typically known as “knock-knock” burglars, sheriff’s officials said the crews are often formed by gang members. The crews use high-end luxury vehicles so as not to raise suspicions when they drive into the middle-class neighborhoods they target for theft, the statement said.

Residents are advised to call 911 if they see a suspicious person or vehicle in their neighborhoods.
