As friends, family, and the community try to come to grips with the shocking murder of a 27-year-old pregnant woman in Paso Robles, investigators have yet identify just what caused her longtime boyfriend to allegedly commit the crime.

Investigators say they believe that Daniel Ruiz Rodriguez Johnson murdered the woman, identified as 27-year-old Carrington Jane Broussard and the 9-month-old fetus she was carrying, but don't know what may have driven him to do it, according to SLO County Undersheriff Jim Voge.

• DOUBLE MURDER Sheriff's investigators say they still don't know what drove Daniel Johnson, 31, to allegedly kill his girlfriend, 27-year-old Carrington Broussard (above), and her unborn child.

"We do not have any information on a possible motive," Voge said at a March 4 press conference.

Voge said the couple was not legally married but had been in a relationship for about six years and had two daughters in addition to Broussard's unborn child. Voge said preliminary evidence indicated that Broussard was stabbed multiple times. The couple's two other daughters were unharmed and have been placed with family members, Voge said.

Johnson was initially arrested in March after he reportedly stole an unoccupied California Highway Patrol vehicle. Johnson led CHP and SLO Sheriff's Office deputies on a chase until the vehicle was disabled with a spike strip near San Simeon and he was subdued using less-than-lethal ammunition, according to CHP reports. After his arrest, Sheriff's deputies went to the residence Johnson was living in, located on the 2800 block of Sorrell Lane in rural Paso Robles, where they discovered Broussard's body.

Johnson is currently in SLO County Jail. At the press conference, Voge said the Sheriff's Office plans to charge him with two murders: Broussard and her unborn child.

While investigators continue to seek a motive in Broussard's death, her family has started a GoFundMe campaign to raise money for her funeral. As of March 6, they had raised a total of $7,770. In a post on Facebook, Broussard's brother, Christofer Jewett, said the response from the public in the wake of his sister's death was a "blessing."

"Such a weight has been lifted from my heart, not because of the money, but because how many random people care," Jewett wrote. "The support of the community. The world isn't just filled with terrible people. There is good out there, thank you all."

Update:

On March 6, the SLO County District Attorney's Office announced that it filed multiple felony charges against Daniel Ruiz Rodriguez Johnson, including two counts of murder. The DA's Office said it believed that the circumstances surrounding the murder make it a capital case, meaning that they could choose to seek life in prison without parole or the death penalty in the case.
