Waco, TX (FOX 44) — Several witnesses have already taken the stand in day one for Christopher Weiss’ trial for capital murder.

Weiss is accused of killing his girlfriend, Valerie Martinez, and their child, Azariah back in 2017.

In opening statements, the prosecution made every effort to tie Weiss to their murders.

The prosecution told the jury Weiss lied when first meeting Valerie using “James” as a fake name.

As “James,” the prosecution explained how Weiss said he was single and was in the military.

Weiss had Azariah with Valerie while being married with two kids.

Prosecutors say Martinez wanted Weiss to help raise Azariah to break the generational curse of being a single parent.

Ultimately, she and their daughter ended up dead at Tradinghouse Lake.

The defense mentioned in their opening statements that no DNA tests tied Weiss to the crime, and there is no weapon directly tying Weiss to the case.

The defense added that people are making assumption.

The first witness testimonies were gut wrenching as individuals described how Valerie and Azariah were killed.

Some in the gallery started to cry seeing the evidence.

Forensic pathologists ruled both of their deaths as homicides caused by bullet wounds to the head.

Texas Ranger Jake Burson later testified how he helped process the crime scene at Tradinghouse Lake and did a four hour interview with Weiss on what he knew.

In a video deposition Weiss told Burson he talked with Martinez the night she was found dead.

Weiss admitted to detectives he cheated on his wife with Valerie and was indenial about Azariah being his child.

Weiss said his life fell apart once his wife found out he cheated.

Weiss didn’t react when detectives told him Valerie and Azariah were killed.

Weiss says he saw Valerie for an hour before leaving around 11 P.M. on November 4, 2017.

In this time period back, Weiss said he wasn’t proud of himself and wanted to be a better man.

Weiss said he wasn’t capable of killing anyone and was trying to be a father figure for Azariah.

Burson told the jury there were discrepancies in Weiss’ timeline of events and the location for his .22-caliber revolver was unknown.

The defense will cross examine Burson Wednesday morning.
