(KCEN) -- The trial is finally underway for one of the men accused of shooting and killing two Waco men in March of last year.
Ricky Cummings is accused of killing 21-year-old Keenan Hubert and 17-year-old Tyus Sneed at the Lakewood Villa Apartments in east Waco.
The prosecution says the shooting was a retaliation for a previous murder.
Today's proceedings mainly focused on that previous murder of Emuel Bowers, who was killed at a Waco park.
The prosecution showed evidence showcasing the friendship between Cummings and Bowers.
It was a very tense morning at the courthouse.
There were many friends and family trying to get in and more than 20 people had to be turned away.
Additional sheriff's deputies and Waco police officers were on hand to keep the peace and to protect Cummings and the jury.
That jury is made up of seven men and seven women, all of which appear to be Caucasian.
Detective Michael Alston with the Waco Police Special Crimes Unit took the stand this afternoon and spoke about both the Bowers murder and the murders in this trial, since he partially investigated both.
He spoke about how the Bowers case had members of that family trying to identify Hubert as a person of interest.
He was looking into that possibility when heard about Hubert's murder.
Alston said, "I just felt like the wind was knocked out of my sails. I felt like I had enough to approach him to find out more about the case."
Now somebody has been arrested and charged with murder in the Bowers case.
And tomorrow in court everyone is expecting to hear details about the murders of Hubert and Sneed.
