ALBANY, N.Y. -- On Wednesday, jury selection in the trial against a man accused of murdering two women began in Albany County Court. Edward Mero is accused of causing the death of Megan Cunningham in 2013 and Shelby Countermine in 2014.

In court documents obtained by Spectrum News, details were revealed about the case the prosecution is presenting.

In these documents, presented by Assistant District Attorney Steven Sharp, there are statements Mero made to investigators and various witnesses. One of the statements Sharp says Mero made while on a date reads, "well you are a firefighter, you could easily get rid of people. Us water guys, we can too."

Mero was an employee with the Albany Water Department.

Megan Cunningham died in a house fire in Albany in 2013. Mero was her roommate and claims he was with her before the fire. Her death had originally been ruled accidental, but became a homicide investigation.

Shelby Countermine went missing in 2014 and her body was found in 2015 in Coeymans in a shallow grave on property run by Albany Water Department. In the documents, Sharp says Mero admitted to having a sexual relationship with her and told police he had last seen her on the day she disappeared.

The documents state there is a witness who says Mero discussed both murders with them. The documents also state another witness, who was an inmate at Albany County Jail with Mero, says Mero admitted to killing Countermine and denied killing Cunningham.

Sharp also put a portion of a statement Mero made to police in these documents when talking about Countermine. It reads in part: " 'I don’t think I killed her' [When asked what that means Mero continued] 'I don’t know, I don’t know as far as when she was leaving, I don’t know what happened. I don’t know if she fell down when she was leaving the house, and I don’t know.' "

In the statement, Mero goes on to say he "kind of blames" himself for Countermine going missing and he talks about blaming himself after his roommate, Cunningham, died.

In court on Wednesday, an assistant district attorney questioned the pool of 21 prospective jurors about whether they could listen to and consider information from witnesses who have criminal pasts or accepted a plea deal in exchange for testifying. 

Defense attorney Cheryl Coleman asked the jurors what their initial thoughts of her client were, and most said Mero seemed shy. She also spoke with the prospective jurors about whether they can be fair and impartial if Mero doesn’t testify. 

Four jurors were sat on Wednesday. Opening statements are set to begin Monday afternoon. Mero has been in Albany County Jail since he was arrested and charged in February.
