HOUSTON -- The trial began Monday for Dr. Robert Yetman who is charged with indecency with a child and is accused of inappropriately touching a 7-year-old boy when he was a patient at Memorial Hermann Hospital in January 2014.

After opening statements, the alleged victim's mother took the stand.

His mother told the jury that while on vacation with her partner, a family member was looking after her four children when her youngest son suffered a complication with his asthma.

He was first taken to Baylor St. Luke's Emergency Center in Pearland and then was eventually transferred to Memorial Hermann Hospital.

During his time there, when the boy's family left the hospital for a few hours, the boy claims Yetman came into his room while he was alone and fondled him.

Defense attorney Stanley Schneider says the doctor was never alone with the boy and that he plans to call as many as 40 people – doctors, nurses and hospital officials – in Yetman's defense.

The Texas Medical Board has temporarily suspended his medical license. If Yetman is convicted, he could face a maximum sentence of 20 years in prison.

The trial continues Tuesday.
