Family members say two of the victims, 25-year-old Dayshia Nixon and her 16-year-old sister, Velvet Archuleta, are in the hospital.
Fresno police say Jacob Velasquez, 24, terrorized three people at the pool in the Sandalwood Apartment complex. Clovis police tracked him down at a complex nearby and turned him over to the Fresno Police Department.
The suspect did not know the victims, before police say the bizarre rampage began.
"He jumped the fence to get to the pool area," said Mark Salazar with the Fresno Police Department. "He walked over to one of the female victims, started talking to the female victims. They thought it was kinda odd, then all of the sudden he stabbed her. At that point he jumped in the pool, stabs the other female, and then exits the pool, then gets into a physical disturbance with a male."
A neighbor who lives in the complex said he heard screaming and went to see what was going on at the pool.
"The first thing we see is one girl on the floor, on her back, bleeding, saying she couldn't breathe and the other girl grabbing her neck. She got sliced in the neck pretty bad."
Tiburcio Garcia is the grandfather of the female victims who were stabbed. He says Dayshia Nixon left his house around 7:00 Monday evening, to hang out at with a friend.
"She took her sister, baby sister with her because they were going to swim," said Garcia. "And that's when this thing happened."
Police believe Velasquez was under the influence of drugs. After the stabbing spree, police say the rather muscular suspect, then tried to take down an officer at police headquarters.
"He then took a swing at our night detective," said Salazar. "The night detective, who stands an athletic 6 foot 5 inches and 250 pounds had to take him to the ground with another night detective and after a struggle he was put into custody again."
Police say the suspect has a criminal history in Bakersfield and Los Angeles which includes resisting arrest and drug charges.
Velasquez is facing three counts of attempted murder and an additional charge for fighting with police.
