CLEARWATER, Fla. — While the search for suspects in the murders of David and Mina Swan in September, 2018 continues, the couple's adult children each still struggle with feelings of horror and denial in the aftermath of the crime.

It’s an unsolved double murder that left a Clearwater neighborhood stunned: a beloved elderly couple shot and killed inside their home.

88-year-old David Swan and his wife, 80-year-old Mina Swan, were shot to death in September, 2018.  Since then, homicide Detective Brian Kanicki has been trying to solve the case.

“This was a very calculated and planned murder," Kanicki explained. "They specifically went to the Swan residence with the intent to kill them."

A horrible discovery

Noel Devine, Mina’s daughter from her first marriage, was the one who found the couple, after a neighbor let her know he hadn’t seen them in a couple of days. 

“When I heard that the papers were building up, I just panicked,” Devine said.  

She drove to her mother’s house, hoping the Swans had taken a last minute trip.  But inside, Devine made the horrible discovery.

“It was just a moment that I would never wish on anyone,” Devine said.  “It’s my mother and I couldn’t help her.”

Searching for a suspect

From the start, Kanicki said there has been no obvious suspect, no sign of a break-in, and not a single item missing from the Swan's home.  

Investigators spent three days gathering evidence and since then, more than 100 people have been interviewed, all in hopes of finding out who could possibly want to kill these retirees. 

“Some cases are made on DNA or fingerprints or ballistics,” Kanicki said.  “I think this is going to come back to good old fashioned police work.”

Among the possibilities, Kanicki said he is looking into the possibility money was a motive.

“While they didn’t live a lavish lifestyle, both of them had investments,” Kanicki said.

"It's not real for me yet"

But David Swan’s daughter from his previous marriage, Julie Swan, said her father, a retired CPA, was a good businessman.

“I want to let people know what kind of people they were,” said Swan. “Dad was the type of person who was true to his word.”

He was also generous, according to Swan, traveling with Mina and other family members on trips around the world.  

“I still think they’re on vacation. It’s not real for me yet,” Swan said.  “I think they’re going to come home one day and I’ll have this horrible story to tell them. But they’re not.”  

Detectives are now urging anyone who ever came into contact with the Swans to come forward and speak with Clearwater Police. The number to call is (727) 562-4141.

The reward for information leading to an arrest and conviction in this case is now up to $50,000.
