Prince George's County Police found a mother and and daughter dead inside a Laurel home following a barricade situation Monday.
The fatal shooting may have stemmed from a dispute over Mother's Day, News4's Pat Collins reported.
Ronnie Lee Rainey, 59, is charged with two counts of first-degree murder in the deaths of his wife, 50-year-old Lisa Renee Rainey (pictured right), and his stepdaughter, 27-year-old daughter, Ariale Chantre Shelton (pictured below).
He is also charged with two counts of first-degree assault.
Ronnie Rainey had apparentedly wanted to take out his wife for Mother's Day on Sunday, but she didn't want to go, authorities said. Lisa Rainey left the home and took her children to a hotel, where they spent the night.
Apparently fearful that her husband might get angry when they returned, Lisa Rainey contacted her daughter's boyfriend, a parole and probation officer, and asked him to meet them at their home in the 16100 block of Malcolm Drive.
When they arrived, Ronnie Rainey emerged with a gun and ordered everyone inside.
The daughter's boyfriend fled, but once the rest were inside, Ronnie Rainey shot his wife and stepdaughter, authorities said.
Police, including SWAT, went to the home after Ronnie Rainey reportedly called police around 10 a.m. saying he killed his family and threatening to kill himself, police said.
When they arrived at the scene, police received another call from the man saying he was leaving the house without the weapon, Collins reported Monday. Rainey surrendered to police a short distance away from the house.
Inside the home, police found the bodies of Lisa Rainey and Ariale Shelton, not far from the front door, Collins reported.
Ronnie Rainey also allegedly fired at his 15-year-old son, but the boy ran from the house and escaped injury, Collins reported. The bullet hit the boy's hat but not his head.
The boy also called 911, but it's unclear when.
In a tweet Monday afternoon, police described it as a domestic-related double homicide.
The Raineys met while serving in the Army, Collins reported. Both were medics and continued to work with the government after leaving the military. They got married 15 years ago.
Debbie Lee, who called Lisa Rainey her best friend for 25 years, said Ronnie Rainey was a coward.
“That’s why he’s a coward, if he shot them and he didn’t shoot himself,” she said.
Rachel Gilbrtz, a friend of the boy, said he is a good kid and a good student.
“It’s hard to imagine what he’s going through,” she said.
