New court documents show that former Orange County Sgt. Anthony Shea, who is accused of killing his wife Lt. Eloilda "Ellie" Shea, used text messages to cover up his crimes, according to an arrest affidavit.

Lt. Eloida Shea was shot and killed in her home on Monday. Her husband is accused of firing the gun.

An arrest affidavit claims Anthony Shea tried to establish an alibi through text messages and surveillance video, alleging he hid his actions by telling detectives it was a suicide.

Ryan Vescio, a former Orange-Osceola homicide prosecutor, emphasized the importance of digital evidence in the case.

"For people committing crimes, one of the best tools to determine what they did and where they did it, and in instances, how they did it, is the phone they carry around with them in their everyday life," Vescio said.

Investigators claim Shea used Ellie's phone to text his phone so he could make it seem like he was away when she was killed.

"It's really the telephone and the digital evidence in this case that refuted Anthony Shea's version of events which, prior to this type of evidence, might have not led to an arrest," Vescio said.

He allegedly told deputies they had been fighting over his affair, saying, "Last night she said, 'Tony, I can't handle it anymore.'"

He claimed they made up the next day, Ellie called in sick from work, and then he took the children out to Publix.

He told detectives when they returned, he found Ellie shot, saying, "I see the gun. It was on her chest."

Detectives claim Shea showed them time stamps on messages between him and Ellie, but they believe her last communication was when she texted her job calling in sick.

They found a Google search on her phone reading, I'm a cop, and my husband sexually assaulted me.'

Detectives say Anthony Shea then sent a message to his phone from Ellie's and seconds later, he accidentally started audio recording for 54 minutes on her cell phone.

Surveillance video captured him driving away to Publix with the kids, and investigators claim when he returned, he finally called 911.

The affidavit says in that audio recording Shea does not become emotional or react to his wife's condition until a dispatcher answers 911.

Anthony Shea left the sheriff's office in August.

Court documents say he resigned due to being investigated for having an affair while on duty.
