Vallejo police on Saturday were trying to figure out what prompted a deadly attack in a home in the early morning hours that badly injured a little boy and left his mother dead.
"An investigation is in progress," Lt. Sid DeJesus said of the assault that took place just before 2 a.m. in the 2000 block of Marin Street. "We're trying to establish a motive. It was a pretty violent attack."
An 8-year-old boy, who was among several other people inside the Marin Street house at the time, made the 9-1-1 call that brought police to the scene, DeJesus said.
"There were three or four other women inside, all of whom said they were assaulted to some degree," he said. "A child called us and said someone had attacked his family."
The injured boy, 5, and his 40-year-old mother were found inside the home with major injuries. The woman succumbed to her injuries en route to a trauma center, police said.
Though police say the victim knew her attacker, the nature of their relationship was unclear Saturday. The young child, while in serious but stable condition in an area trauma center, suffered injuries so severe he can't be interviewed by police at this time, DeJesus said.
The deceased woman's name is being withheld pending notification of family, police said. Police on Saturday were also not revealing the weapon used in the attack, but DeJesus said the scene was gruesome.
The surviving victims in the home identified Darryl Wakefield, 43, of Vallejo, as the assailant, and he was located on Springs Road in East Vallejo and taken into custody without incident at about 8:40 a.m., DeJesus said.
Wakefield, who was arrested on suspicion of murder and attempted murder, is on parole and has an extensive, violent criminal history, DeJesus said.
Having survived what DeJesus called "a senseless attack," it is not immediately clear what will happen with the child, though police will "take all the steps necessary to ensure the child's safety when he's released from the hospital."
This is Vallejo's 10th homicide of 2014, including one officer-involved shooting.
