HOUSTON A fourth suspect in an alleged murder-for-hire plot against a Bellaire socialite appeared in court Friday morning on aggravated assault charges.

Nhut Nguyen is accused in one of three attempts on Yvonne Stern s life.

Police believe he participated in the second attempt, in which someone shot at Stern after knocking on the front door of her Bellaire home.

She was not hurt in that incident, but was later shot in the stomach and seriously injured.

Authorities believe Stern s husband, prominent Houston attorney Jeffrey Stern, was having an affair with Michelle Gaiser, who is accused of hiring hit men to kill the socialite.

Gaiser and two others have been charged with solicitation of capital murder in the case.

But this was not Nguyen s first brush with the law, according to documents uncovered by 11 News.

Nguyen was convicted in 1998 of murder and racketeering in Massachusetts.
