The following was compiled from Renton Police Department case reports.

Two men knocking on doors in search of a chihuahua named “Cujo” at about 11 a.m. Oct. 16 didn’t fool a Renton Police officer, who surmised they might be burglars casing the neighborhood.

Several residents had called 911 to report the men’s suspicious activity, which might mean they were trying to find out who wasn’t at home.

They gave a convoluted story that they lived in Auburn but were in Renton on South 22nd Court looking for Cujo.

A records check showed the 27-year-old Auburn man had a state felony warrant for escape.  He had a theft warrant, too. The 19-year-old Auburn man had a clear record.

After arresting the older man, officers found a a black crystal-like substance wrapped in aluminum foil in his wallet. It tested positive for black-tar heroin; there was probable cause to arrest him for drug possession.

The 27-year-old admitted the two were aiming to burglarize homes, but there was no evidence that they had. He needed money for his drug habit and admitted Cujo didn’t exist. He was booked into the SCORE regional jail.

In his backpack, the 19-year-old was carrying a large hand tool professionally crafted to smash windows. He was allowed to leave.

No key but car still unlocks

The Renton man was standing next to his two-door sedan, looking for his keys, at The Landing Oct. 14 when the car’s lock disengaged.

Apparently, someone had stolen the keys from his backpack while he worked out.

He noticed three men standing in front of LA Fitness, looking at him. They told him they didn’t have anything to do with his missing keys.

His father brought him an extra set of keys.

State Patrol to test white substance

The Washington State Patrol crime lab will test 77.7 grams of a white powder substance found Oct. 14 in a desk at the Renton Boeing plant.

The bags of the substance were found while a desk was being cleaned out to be moved to another area.

A Boeing security manager brought the substance to City Hall so that a police officer could field test it. Test results proved inconclusive for cocaine.

The State Patrol testing may not occur for weeks or months because it’s a low priority. An investigation is pending until it’s determined whether a crime occurred.

Teens cited for theft at Walmart

Two Tukwila teenagers were cited Oct. 18 after they were stopped at Walmart for failing to pay for beauty products and linens they told an officer they needed.

Value of the items was $256.

The two walked into the store on Rainier Avenue South and took several Walmart plastic bags from a register. They concealed the items in their purses and the plastic bags.

They were trespassed from Walmart for a year; the case was referred to the Renton prosecutor.

Juveniles scare neighborhood

A business owner saw a group of juveniles running Oct. 18, after he heard the sound of breaking glass in the retail portion of his business.

In investigating an officer found that other businesses and pedestrians knew of the juveniles, had similar run-ins and feared them.

The owner of the business in the 2800 block of Northeast Sunset Boulevard found a rock on the floor. Damage was estimated at $500. At least one of the juveniles has damaged the business before.

Movie-goers’ car broken into

Someone broke into a car Oct. 19 parked at the movie theaters on East Valley Road, taking a woman’s purse.

A window on the car was smashed. Damage was estimated at $250.
