Police in Hallandale Beach, Fla., are asking for the public’s help in identifying a woman on a surveillance tape in hopes of catching a break in the case of a Toronto couple found slain there last month.

David Pichosky, 71, who was known as Donny, and Rochelle Wise, 66, were found dead in their Hallandale Beach condo on Jan. 10 after failing to make a scheduled lunch date with a neighbour.

According to a short statement released Thursday, an unidentified woman was spotted carrying an item toward the rear of the retired couple’s residence at 9:45 a.m. on Jan. 9. Police say the mystery woman then returns to the front of the house empty-handed.

The footage – which will be made available on the police department’s website – was captured by a neighbour’s electronic video surveillance.

Police aren’t calling the woman a suspect, nor are they identifying the object in the woman’s hands.

The woman in the video is about 5'4 and heavy set.

"This woman appears to be wearing a black jacket, grey pants, blonde hair and a pony tail [and] is seen walking next to the Pichovsky-Wise residence,” Sonia Quinones of the Hallandale Beach Police told CTV Toronto. “She's carrying something in her arms; she walks right alongside the residence towards the rear. When she returns from the back of the residence she then is seen walking back towards the front, but this time she's empty-handed.”

Quinones added that police have showed the video to local residents but no one could identify the woman.

In late January, law-enforcement officers from Florida spent four days in the Toronto area, interviewing the couple’s family and friends to learn as much as possible about the victims.

Pichosky and Wise split their time between Toronto and Hallandale Beach, an affluent waterfront community in east Florida located between Miami and Fort Lauderdale. Wise was well-known in Toronto as the founding director of Crestwood Valley Day Camp and as vice-principal at Bialik Hebrew Day School.

Police have remained tight-lipped about the murder investigation, and have not released the couple’s causes of death or a possible motive for the crime, saying releasing further details might hinder the investigation.

The double-murder has shocked the gated Florida community, popular with retirees and snowbirds.
