AUBURN, CA — Former Major League Baseball pitcher Dan Serafini was sentenced to life in prison without the possibility of parole for murdering his father-in-law and attempting to murder his mother-in-law in a 2021 ambush-style shooting at a Lake Tahoe-area home.

A Placer County jury previously found Serafini, 51, guilty of fatally shooting 70-year-old Gary Spohr and seriously wounding Spohr’s wife, 68-year-old Wendy Wood, on June 5, 2021, at their home on the lake’s west shore. Wood survived the attack but died a year later.

In a statement obtained by The Associated Press, Placer County District Attorney Morgan Gire said that Spohr and Wood were loving grandparents and detailed how Serafini’s crimes had affected the couple’s family members and friends.

“The impact of this attack has extended far beyond the immediate victims, deeply affecting family members and the broader community, and highlighting the lasting harm caused by deliberate violence,” Gire said.

On the day of the shooting, Serafini’s wife, the victims’ daughter, had taken the children to the lake to visit their grandparents.

Prosecutors said the deadly ambush stemmed from a dispute over a $1.3 million investment in a ranch renovation project. The victims had reportedly contributed the money.

In one text message shown in court, Serafini wrote, “I’m gonna kill them one day,” referencing a dispute over $21,000, prosecutors said.

He also sent other threatening messages, including “I will be coming after you” and “Take me to court,” according to ABC10.

Jurors also found Serafini guilty of several “special circumstance” sentencing enhancements, including lying in wait, use of a firearm, and that the attack was willful, deliberate and premeditated. He was also convicted of first-degree burglary.

Prosecutors had also charged Serafini with child endangerment, saying he put his infant and toddler sons at risk by having a gun in the home. Jurors found him not guilty on that count.

The case also involved a second defendant, 33-year-old Samantha Scott, who pleaded guilty to being an accessory in February, according to the New York Post.

A left-hander, Serafini was a 1992 first-round pick for the Minnesota Twins. He also played for the Chicago Cubs, San Diego Padres, Pittsburgh Pirates, Cincinnati Reds and Colorado Rockies, pitching for six MLB teams over seven seasons.
