The couple gunned down Wednesday morning in downtown San Diego was likely headed to the courthouse. The husband and wife had separate restraining orders targeting the wife’s spurned lover, and they were due in court. The pair didn’t make it. Rachael Martinez, 31, and Jose Medina, 39, were ambushed in their parked vehicle two blocks from the courthouse. Their alleged killer then engaged Harbor Police officers in a shootout less than a mile away in Little Italy. A police officer was shot and injured and is now recovering. The gunman was mortally wounded. On Thursday, San Diego police released the names of the couple and their alleged killer, 26-year-old Christopher Farrell. They also laid out details behind the violent spree. According to court documents, Martinez had been romantically seeing Farrell for a few weeks before her husband found out and confronted him in late September. Shortly after that, Martinez alleged in an application for a restraining order, she met with Farrell to ask him to back off. It ended in violence, she alleged. Days later, on Oct. 4, she filed a report with the San Diego Police Department about the incident, alleging domestic violence, including false imprisonment and sex crimes. San Diego police homicide Lt. Jud Campbell said Thursday in a news release that the investigating officers obtained an emergency protective order. The same day, police officers located Farrell at a Metropolitan Transit System office in Barrio Logan, where he worked as a contract security guard with Inter-Con Security, police said. Farrell was fired, and his work firearm was confiscated. He was booked into San Diego County Jail. Two people were shot and killed in this gray vehicle on Union Street near A Street on Wednesday.

Three days later, on Oct. 7, a judge granted Martinez a temporary restraining order against Farrell. The next day, Martinez’s husband obtained a separate temporary restraining order against Farrell. Court documents indicate that an attempt by sheriff’s deputies to serve both restraining orders to Farrell at work failed — he’d already lost his job. Campbell said it was unclear at the time of the shooting if Farrell had been served with the restraining order. On Wednesday, Martinez was supposed to be at a hearing regarding the restraining order matter at 9 a.m. The 911 calls started coming in just after 8:22 a.m. Callers said people had been shot while sitting in a car on Union Street, about two blocks north of the courthouse. The gunman, clad in a green shirt and blue jeans, had run off. Police fanned out to search, and a helicopter circled the area, announcing his description. A passerby spotted Farrell ducking behind an electrical box near Juniper Street and Kettner Boulevard and flagged down nearby Harbor Police officers. Four Harbor Police officers approached the man. Campbell said Farrell, appearing to use the electrical box as a shield, pointed a gun at the officers and opened fire. One was struck in the hip. Two bullets hit a Harbor Police patrol car.

Alfred / The San Diego Union-Tribune) Two officers fired back, and Farrell was struck multiple times. Campbell said the entire encounter lasted less than 90 seconds. Farrell died at a hospital less than an hour later. Behind the electrical box, investigators found a semi-automatic handgun and an empty magazine on the ground. Three more magazines were clipped to Farrell’s pants. They also found multiple folding knives and a tactical flashlight. The wounded officer, who did not open fire, is continuing to recover, Harbor Police Chief Magda Fernandez said in a statement Thursday afternoon. His name was not released. Fernandez said “his family are grateful for the support they are receiving and respectfully request privacy at this time as they process and begin healing from this traumatic incident.” The officer had previously been employed with the San Diego Police Department for about a year but was hired onto the Harbor Police force in September, Campbell said. The names of the officers who opened fire on Farrell also have not been released, but San Diego police officials said they are six- and nine-year veterans of the department. The families of the couple have also asked for privacy, Campbell said. Court documents indicate Martinez and Medina had four children, ranging from 3 to 15 years old. By Thursday afternoon, a small memorial of candles, flowers and offerings of water and fruit had appeared on Union Street not far from where the couple died. The candles had been lit.
