Four suspects have been arrested for the June 28 double homicide that took the lives of a brother and sister, while three more suspects still at large are considered armed and dangerous, a Mountain View police sergeant said Wednesday.
Maria Teresa Sanchez-Aquino, 27, and her brother Omar Aquino, 24, were found shot to death the morning of June 28 in their Plymouth Street home, Sgt. Ken Leal said.
On Thursday three of the suspects were arrested after a judge issued warrants, Leal said. Michael David Adams, 20, was arrested at the Valley Fair Mall in San Jose and Nicory Marquis Spann, 18, was arrested by detectives in Fremont. Both are residents of San Jose.
Victoria Frances Thompson, 20, was arrested in her hometown of Morgan Hill on a warrant and a 15-year-old girl was arrested Thursday as well.
Three other suspects remain at large: 19-year-old Kim Thien Pham from San Jose or Morgan Hill, 20-year-old Kenneth Ivory Thomas from Campbell and a 17-year-old girl. The three suspects are considered armed and dangerous, because the handgun used in the murders has yet to be discovered.
Leal said his detectives are still not positive which of the suspects is the shooter, or shooters. He also would not confirm whether all seven suspects were in the home at the time of the shooting, or whether they were merely in the vicinity of the home.
"In my experience it's unusual to have so many suspects," Leal said.
Of the seven suspects only two are not charged with murder, Leal said. Thompson and the 17-year-old girl are both facing charges of conspiracy to commit murder, while the other five suspects are charged with conspiracy to commit murder and two counts of murder.
Police spokeswoman Liz Wylie said it appears Sanchez-Aquino made a 911 call that was answered by a California Highway Patrol dispatcher at 3:54 a.m. The call, reporting a break-in, was lost before it was connected to Mountain View police.
The CHP dispatcher claimed the caller gave an address on "Clemon'' Street, which is not a valid address in that city.
Dispatchers and officers, who had the Sanchez' phone number but not the address, were still investigating the call when they received reports of shots fired in the 1900 block of Plymouth Street at 4:53 a.m.
Responding officers found Sanchez-Aquino and Aquino dead of gunshot wounds inside the home, Wylie said.
Sanchez's 8-year-old son was found unharmed and asleep in another room of the home. He is now being cared for by relatives.
The house appeared to have been ransacked, and Leal said that police believe one of the motives for entering the home was robbery. He added that no drugs or drug paraphernalia were found in the home.
The suspects appear to have been acquaintances of Aquino but the relationship between them cannot be revealed at this time, Leal said. Police are investigating possible drug or gang aspects of the crime, but did not release a definitive motive for the murders.
The case is ongoing, and a Santa Clara County judge has sealed many of the documents in the case so large chunks of information are not available to the public, Wylie said.
