Robbery Suspect Leaves Calling Card : Burbank: Police say he got $100 from a fast-food clerk and then dropped his ID outside while fleeing.

Randolph Aguilar’s attempt to rob two stores led to a string of misadventures that ended when he left an obvious clue--his California identification card, complete with his name and address, Burbank police said Wednesday.

Aguilar threatened clerks with a fake pistol made of tape-wrapped plastic tubing, police said. At his first stop, a skeptical shoe store clerk refused to go along. And although Aguilar then got $100 from a Pioneer Chicken restaurant, he dropped his ID card in the parking lot, police said.

Card in hand, officers were waiting for Aguilar by the time he got back to his Atwater Village home Tuesday afternoon.

And once in police custody, he confessed to the March 28 robbery of a Burbank donut shop, Sgt. Don Goldberg said. Aguilar, 41, a drug addict who stole money to support his habit, also is suspected in other robberies in Glendale and Los Angeles, Goldberg said.

On Tuesday, Aguilar first attempted to rob a Kinney Shoes store on Victory Boulevard, lifting his shirt to reveal a bulge in his waistband that he said was a gun, Goldberg said. The tubing wrapped in black plastic tape looked similar to the butt of a semiautomatic pistol, he said.

When the clerk refused to give him money, Aguilar punched her several times in the face and ran out of the store about 12:30 p.m., Goldberg said.

Less than 30 minutes later, Aguilar walked into the Pioneer Chicken restaurant, where cashier Maritere Salas was talking to her father, Fernando Salas.

Maritere, 17, said Aguilar first approached her father and whispered that he had a gun and wanted money.

She said she could not hear Aguilar and, thinking he was a customer who needed help, asked him to repeat himself.

He did, raising his shirt to show her the bulge in his waistband.

“At first I didn’t believe it, but then I was really scared,” said Maritere, who has worked at the restaurant for about eight months.

She said she handed Aguilar about $100 from the cash register. Aguilar ran to the parking lot and Fernando Salas followed while Maritere called police.

Aguilar reminded Salas of the bulge in his waistband to keep him at bay, Goldberg said.

Aguilar took off his shirt while trying to remove the rear license plate from his car, dropping his identification card and the cash he had taken from the restaurant, Goldberg said.

He picked up the cash, but left the card and sped off.

Police found the identification card when they arrived and were at Aguilar’s house in the 4100 block of Chevy Chase Drive when he pulled into the driveway about an hour later.

He was being held in lieu of $10,000 bail.
