When neighbors heard the gunshots they ran over to the house and found that two people had been shot and the victims' toddler was nearby.
"My neighbor said he knocked on the door and he ran inside and got the baby and went to the neighbor's house," said a neighbor.
Vallejo police say a 30-year-old man and 28-year-old women were killed. Neighbors say carloads of family members descended on the neighborhood when they heard the news and they were very vocal with their grief. One woman fainted and had to be treated by paramedics and they heard another man describing the victim as pregnant.
"He was calling all of his friends saying 'my sister had been shot, I don't know why this would happen to her' and that she was pregnant," said neighbor Jeanette Canessa.
A woman who knows the couple said the woman was pregnant with twins, but police said they won't know for sure until an autopsy is performed. Investigators have not made any arrests in the shooting.
"Witnesses said that after the shooting two black males ran southbound on Atherton running away from the scene," said Vallejo Police Lt. Lee Horton.
Police have not released any more information about the victims, but people who knew the man gathered outside the crime tape and comforted each other. At least two women said they were his girlfriends.
"He was a good man, family oriented, who did his thing. I just can't understand how this happened," said T. Simmons, who is a friend of the victim.
Some of the people living here said they now feel nervous for their safety. The police said they think it was a targeted attack.
"I think that the neighborhood is fine, I don't think it was a random event," said Horton.
Police won't say why they think this couple was targeted and their names have not been released yet. Police said there were not any signs of forced entry into the house.
The case remains under investigation. Anyone with information is encouraged to contact Vallejo police at (800) 488-9383.
