HATTIESBURG, MS (WDAM) - In May 2011, Pat and Robert Morrison were found beaten to death in their Lamar County home.
Since then, several persons of interest gained attention from authorities, however no arrests were made and the case has gone cold.
"We received a call last night (May 23, 2011) a little bit after 9 p.m. from a family member of the deceased," Lamar County Sheriff Danny Rigel in a 2011 interview said. "They went to the residence to check on them, they had not heard from them in a little while, so they went to check on them, saw the back door broken in, they saw bodies lying on the floor inside the residence."
The couple was found dead inside their home at the corner of Lamar Avenue and Fox Terrace, just outside the Hattiesburg city limits.
Pat and Robert Morrison, both 82, were well loved and respected in the community. Robert Morrison worked for Mississippi Power for 33 years and spent 30 years in the Navy prior to that. Pat Morrison worked at Fine Brothers Madison Company for 25 years before retiring.
Autopsy results revealed that the couple died from blunt force trauma, according to Rigel.
During the investigation, family members said they last heard from the couple Sunday, May 22, 2011 after church, and had exchanged emails the next night, Monday, May 23, 2011.
"We conferred with other family members and determined that certain items are missing from the residence, but as far as the crime scene, details of the crime scene, or what items were missing that is part of the investigation right now," said Rigel in 2011.
During the investigation, members of the Hattiesburg Police Department Crime Scene Unit were brought in to help conduct the investigation.
Shortly after May 23, 2011, Hattiesburg Police said there could possibly be a link in the Morrison murders with the May 28, 2011, shooting death of Edward Cameron. Cameron, 42, was killed at Collectors Point Pawn Shop on Corinne Street in Hattiesburg.
During the Cameron investigation, police said they believe that at least one of the people involved could be linked to the Morrison murders, due to evidence that was discovered during the investigation.
According to Hattiesburg Police, Cameron was killed in an apparent robbery attempt.
Drakkar Fleming and Gerald Taylor were arrested and charged in that crime. Fleming later pleaded guilty to manslaughter in August 2013, and Taylor was convicted of accessory after the fact of murder in 2013 for the role in Cameron's murder.
Breiana McCantz of New Orleans, was also charged with accessory after fact in Cameron's death.
None of the persons of interest were ever charged in the Morrison murders.
More than five years later, authorities are still searching for leads in the case.
"We've looked at it from every angle that we can, and we are never giving up hope, matter of fact, we have also called in some experts in cold case investigations to look at it with a different set of eyes from a different angle maybe, cause the more people you can get to look at this, you can see something that somebody overlooked," Rigel said.
The Morrison family released this statement Monday in hopes of advancing the cold case.
Rigel said no matter how small the detail may be, anything that anyone may have seen or can remember could be the break in the case that is needed.
"Until we make an arrest it's never going to be over," Rigel said. "When we work on a murder, we speak for those who can't speak for themselves, and I take it very personally, all of my investigators and detectives take it very personally and we are going to make an arrest, we're not ever giving up; we are going to solve this case."
