Man charged in string of bank robberies

A man suspected of robbing 10 Honolulu banks and described as walking with a waddle was charged in federal court on Wednesday.

Wallace J. Silva Jr. was charged by criminal complaint for multiple bank robberies occurring from Dec. 2 to Dec. 27. He was arrested Tuesday.

Silva is also known as Wally Silva, Walter Spinot, Walter Silver, Robert Burrows and Adam Richards, the complaint said.

The complaint alleges Silva violated supervised release and escaped from Mahoney Hale Residential Reentry Center.

An FBI agent’s affidavit said that in the first robbery, on Dec. 2 at the Kapiolani branch of First Hawaiian Bank, Silva threatened the teller in a note saying he had a weapon, and was given $1,000.

Tellers described Silva’s walk as a speed walk with a waddle and a wobble.

The victim complied and the suspects fled with an undisclosed amount of money. Police said there were no injuries.

Lost hikers signal fire crew with whistle

A group of hikers lost in the dark on an Aiea trail used a whistle to signal fire rescue personnel Wednesday night.

Honolulu Fire Department Capt. Kevin Mokulehua said the hikers were on the Aiea Loop Trail when they called the fire department at 6:34 p.m.

The party of two women, a teenage girl and a female toddler were unable to find their way back to the trailhead due to darkness, Mokuleha said in an email.

Fire personnel found the hikers at 7:21 p.m. and escorted them down the trail.

One of the hikers used a whistle to help HFD personnel locate them, Mokulehua said.

No injuries were reported.
