Folsom police released new details Friday about the attack that killed a 5-month-old boy and left his mother in critical condition.
Investigators said the suspect, 20-year-old Jose Reyes Torres, stabbed his infant cousin Roberto Varela and aunt Arela Aguilar Thursday afternoon. When police arrived at the scene, Torres was shot and later died.
On Friday, people stopped by to leave candles and stuffed animals outside the victims' apartment building.
"Hopefully at least it lifts the family's spirit in some way or another to know there's good people out there 20 that are thinking about them 22 even if they don't know them," neighbor Chris Herrera said.
Herrera never knew his neighbors, but when he learned about the attack, he wanted to add something to the small memorial outside their home to honor the little boy's memory.
Police said the first officer arrived at the scene of the attack within minutes. The officer fired a single shot at Torres, who continued to fight officers even after he was hit. Torres died while being transported to the hospital.
Police said interviews with witnesses led them to believe that Torres may have been trying to commit suicide by provoking police.
"We always are looking for answers, just human nature, we want to understand why things happen," Folsom Police Officer Andrew Bates said. "Unfortunately, in a case like this -- where a five-month-old baby was stabbed -- we may never have a suitable answer as to why someone would do something like that."
Roberto was just a few days shy of turning 6 months old. Family members said they are in the process of setting up a memorial fund for the two victims.
