SAN ANTONIO -

A man was hospitalized after he was stabbed three times in the lower back by another man who was with his sister-in-law.

Detectives say the victim went to visit his brother around midnight at a home in the 2400 block of Pinn Road, but found another man with his brother's wife.

He got into an argument with his sister-in-law and police say her companion intervened and stabbed the victim.

The victim's sister-in-law and her companion fled the scene. The victim told police he did not know the suspect, but gave officers a description.

The victim was taken to the hospital in critical condition, but was upgraded to stable a few hours later.

As of 8 a.m. Thursday, police had not located the two people who fled the scene or the victim's brother.
