That’s definitely a possibility, IMO.
I find the following interesting also:
“Bexar County Sheriff Javier Salazar told reporters at a press conference the two girls appear to have been killed, although it is too early to speculate if the third victim, identified as 37-year-old Nichol Leila Olsen by the
San Antonio Express-News, died as a result of homicide or suicide. All three had died from gunshot wounds.
‘We’re hoping as this investigation unfolds it will be able to shed more light on not only what was going on last night, but also what may have happened this morning,’ Salazar said. He added that all three victims were related to each other but did not confirm how.”

“Salazar said the girls’ deaths appeared to be homicides, but investigators are reserving judgment on whether the woman’s death was a homicide or suicide pending further investigation.”

What would make it more difficult to tell if a death was due to a homicide or suicide?
