Washington authorities are searching for an "armed and dangerous" former school resource officer who is accused of killing his ex-wife and 17-year-old girlfriend and abducting the 1-year-old son he shared with his girlfriend.

Elias Huizar, 39, is accused of fatally shooting his ex-wife, Amber Marie Rodriguez, outside William Wiley Elementary School in West Richland around 3:30 p.m. local time on Monday, according to local reports and the West Richland Police Department.

When police conducted a search at Huizar's home on South Highlands Boulevard later that day, they reportedly located his deceased teenage girlfriend, Apple Valley News reported.

Later on Monday, Washington State Patrol issued an Amber Alert for Roman Huizar, the suspect's 1-year-old son, whom he reportedly shared with his minor girlfriend. Police believe Huizar may be traveling to Mexico in a silver 2009 Toyota Corolla, license plate No. CBZ4745, with the 1-year-old boy.

One of Rodriguez's friends described her as "sweet and kind" in a Monday Facebook post.

"I will miss your broker calls and how you always bragged on your babies. I'll never forget when we first met and real estate was your path to freedom for you and your boys," the friend wrote. "Nobody deserves what you went through. May the full force of justice be served. This tragedy has rocked our tiny town and I can only hope that this sheds light on what's wrong with our system! You will be missed Amber!"
