Last week, 16-year-old Jose Murillo-Sosa stood trial for allegedly killing Lori and Adrien Rountree two years ago.

The women were stabbed more than 60 times inside their home in south Nashville.

For juror Matthew Slater, he said it came down to the lack of evidence proving that a third person was at the crime scene the night of the murders.

DNA and fingerprint evidence was what the defense hung their case on, calling no one to the stand, not even Murillo-Sosa himself.

All 14 people on the jury agreed that Murillo-Sosa was not guilty of the killing.

But prosecutors tried to show Murillo-Sosa was there, connecting him with a bloody fingerprint and DNA.

Slater said he felt the DNA didn't prove anything, as it only had five points out of 13, just showing that the DNA was from a man.

"It was not really showing if he was there during the murder or if he showed up after it," Slater said. But the district attorney said the fingerprint was irrefutable evidence

Slater said he believes that Murillo-Sosa was in the home, but the evidence presented to him and the other jurors didn't prove when in relation to the murders.

"His fingerprints were there. He's a neighbor," Slater said. "It didn't give a timeline. It didn't show when he was there."

In a phone interview Thursday, another juror said that the judge informed each juror that his or her job was to prove beyond a reasonable doubt that Murillo-Sosa was guilty of the crime. She said that after seeing all the evidence presented, she still had doubts, and that there were other fingerprints at the scene that no one could identify.

Murillo-Sosa is being held in federal custody. He is scheduled to be deported back to Honduras for the second time.
