New surveillance video shows accused killer Lois Riess at a hotel in Ocala, Florida, and driving what appears to be the vehicle she stole from the woman killed on Fort Myers Beach.
Police say Reiss targeted the woman because the two had similar appearances and Reiss may have wanted to steal her identity.
Riess is also accused of murdering her husband, David, in Minnesota before heading south to Florida.
In a CBS report, Marceno says that although Riess "may look like anyone's mother or grandmother, she's an absolute cold-blooded murderer".
A national manhunt is under way for Riess, who is considered armed and unsafe and should not be approached.
Officers did, and found him dead of gunshot wounds at the worm farm on March 23, the sheriff of Dodge County said. Her personal information, including credit cards, are all missing.
Riess, who is considered armed and unsafe, is believed to be driving Hutchinson's white Acura TL with a Florida license plate of Y37TAA.
Anyone who sees Reiss is urged to call 911, and anyone with information on her whereabouts is urged to call the Minnesota Bureau of Criminal Apprehension or Florida authorities.
From Iowa, police believe, Riess drove to Lee County, Florida.
But on the very last day of her trip, she met Riess and wrote on Facebook, "I'm staying another night".
The obituary for David Riess was published last week, and mentioned his children and grandchildren, but not wife.
"It's just evil that flowed through".
On April 9, police found Hutchinson shot to death at the condo.
"Riess' mode of operation is to befriend women who resemble her and to steal their identity", Bio said at a press conference on Friday.
Authorities warned that, when she runs out of resources, she may kill again.
