MURPHYS -- The man Calaveras County Sheriff's Deputies say shot his two children before killing himself had a criminal record involving his estranged wife.
Phillip Marshall, 54, shot his his children Alex Marshall, 17, and Macaila Marshall, 14, as they slept on the couch of their Murphys home sometime between Thursday when they were last heard from and Saturday when their body's were discovered, authorities said.
On Monday, investigators learned the Marshall family had prior law enforcement contacts with the sheriff's office, according to Sgt. Chris Hewitt.
In November 2008, Phillip Marshall filed a crime report against his estranged wife, Sean Marshall, for burglary. A month later Sean Marshall and her sister, Erin Chamberlain, filed a complaint against Phillip Marshall for battery.
According to reports, Phillip became involved in an argument with Chamberlain outside of Sean Marshall's house in Murphys, Hewitt said.
The argument started because Phillip Marshall wanted to see his daughter, Macaila. During the argument Phillip allegedly slapped Chamberlain in the face.
Phillip Marshall was ultimately arrested and booked into Calaveras County Jail on the charges of battery, disturbing the peace, and making annoying or harassing phone calls.
The investigation is ongoing and a motivation for the murder-suicide is still being examined.
Last weekend, the children and Phillip Marshall were all found with a single gunshot wound to the head. Foul play by outside persons has been ruled out, and evidence at the scene confirmed that Phillip Marshall was the shooter, Hewitt said.
The time of death is still under investigation.
