Mother of murder victim takes stand in trial

Ryan Yearley, 21, shot to death Thanksgiving Day 2012

SAN ANTONIO – The mother of a murder victim was the state's first witness Tuesday in the trial of the man accused of killing her son.

Ryan Yearley, 21, was shot to death on Thanksgiving Day 2012.

His girlfriend's brother, 20-year-old Jesus Rivera, is on trial for the murder.

Yearley's mother said the men were best friends and the murder is a mystery to her.

She said she suspects drugs were involved.

When she arrived at the home where he was killed that day, she was told that her son's body was in a garage behind the home.

If he's convicted, Rivera faces a maximum sentence of life in prison.
