Allison Sue Johnston, age 16 months

Tara Shay Johnston, 29, and her 16-month old daughter, Allison Sue Johnston, were found shot to death in their Oklahoma City home.  The father was being sought for the shooting.  He then turned up dead in Las Vegas, Nevada, apparently after killing himself by cutting his wrists and ankles.

From the article:

Investigators in Oklahoma believe Johnston killed his wife and child before flying to Las Vegas on Sunday, according to Fox affiliate KVVU-TV. 

"We thought the marriage was great," Tara Johnston's uncle, Bill Lisby, said in an interview with FoxNews.com.

"We didn’t see anything wrong ... He took care of Tara and the baby. Allison was his pride and joy. He was really liked within the family," said Lisby, who described Johnston as "really polite" and "clean cut." 

Lisby said the couple had met while working together in a restaurant that Johnston had managed. The two have been married for a few years, he said. 

The man's father, Charles Johnston, reportedly wrote on his Facebook page that his son killed himself by cutting his wrists and ankles. 

Police discovered the bodies of Tara Johnston and her daughter after receiving an anonymous tip that two people were dead inside the family's home near Oklahoma City.
