A 16-year-old girl was at her San Mateo home Wednesday night when an armed robber entered her backyard on the 3200 block of Verdun Avenue, according to the San Mateo Police Department.
Matthew Nguyen, 22, of San Mateo, was arrested for the robbery after 5:40 p.m. on the rainy night, said San Mateo police Sgt. Dave Norris.
The young girl was inside her home at her dining room table when she was startled to see a man identified as Nguyen a few feet away in her backyard, Norris said.
He pointed what appeared to be a black handgun directly at her and demanded money. The girl screamed and her father came downstairs and immediately called police, Norris said.
The man did not enter the house but was handed a small amount of money through the door before fleeing, Norris said.
More than 20 police officers responded and called nearby residents warning them to stay inside and be on the lookout for the suspect, according to police.
“A fast call to police was really instrumental in getting us there quickly,” Norris said.
Within a block of the residence, Nguyen was found with a realistic-looking airsoft pistol and other evidence linking him to the crime, Norris said.
The circumstances leading up to his arrest were challenging due to the rainy conditions and the nearby homes being up against a hillside, Norris said.
“These officers were doing some really good work under some really adverse circumstances,” Norris said.
Although the incident appears to be isolated, police are still determining if Nguyen may be involved with other crimes, Norris said.
