TARPON SPRINGS, Fla. — Law enforcement continues to search for a possible fourth victim connected to the triple homicide in Tarpon Springs. 

Three people and three dogs were found dead on New Year's Day in a mobile home on Juanita Way in The Meadows Mobile Home Park, located at 505 Anclote Boulevard.

Police say the suspect Shelby Nealy allegedly killed his wife's father, mother, and brother — identified as Richard Louis Ivancic, 71, Laura Ann Ivancic, 59, and Nicholas James Ivancic, 25.  

Now police are searching for his wife, Jamie Ivancic, 21. 

Authorities got a lead about a house Nealy and his wife used to rent in Port Richey.  Sheriff's investigators and forensic experts spent hours at the house on Friday, apparently looking for a possible body. 

Neighors living near the home on Norwood Avenue said they were surprised to see the community covered in crime tape. 

"It was full of police officers and forensics, dogs, things like that," neighbor Richard Hillebrand said. 

They also said they never noticed obvious signs of trouble at the house when the couple lived there, but they say Nealy struck them as strange.

"I wasn't specifically shocked, I just kind of figured that something like this was doomed to happen," Hillebrand said. 

"He didn't really let the kids out much. He was weird, you know, something was going on in his mind," neighbor Mike Stockdale added.  

Nealy was arrested in Ohio on Thursday in connection with their murders.  On Friday, Tarpon Springs police said during a news conference that Nealy admitted to his involvement in the murders. 

Police have not released a motive for the killings and haven't said if they found anything at the house in Port Richey.
