A 45-year-old woman — apparently killed in a La Habra restaurant by her ex-boyfriend before he turned the gun on himself — had filed a temporary restraining order against him in September, according to court documents obtained by the Southern California News Group.
The man, 35-year-old Jonathan Wang of Long Beach, was also a defendant in a domestic-violence case in Long Beach stemming from a July 15 incident at his home involving the same woman, Jacqueline Medrano of Covina, according to Long Beach City Prosecutor Doug Haubert.
It was not known how long Wang and Medrano dated, but the temporary restraining-order documents include claims by Medrano that Wang would threaten her and her family members. In one instance, she said, he punched her in the mouth, causing a laceration.
La Habra police have said Medrano was eating inside the Gui Gui 9292 Korean BBQ restaurant in the 1200 block of West Imperial Highway just before 6:45 p.m. Tuesday, Oct. 14, when Wang walked in, shot her, then fatally turned the gun on himself.
“If the news reports are true, this is a grave reminder of the seriousness of domestic-violence cases,” Haubert said in a statement. “That this happened during Domestic Violence Awareness Month shows we still have a long way to go to prevent tragedies like this from happening.”
The domestic-violence case against Wang in Long Beach stemmed from a July 15 confrontation in which he allegedly “punched Medrano one time in the mouth, grabbed her by the front of the neck, pushed her down to the ground, then held her down by the back of her neck” until he pushed her out of the room, according to a statement from Medrano provided by Haubert.
A Long Beach officer went to the Marker Street address in North Long Beach in response to a domestic-violence call, Haubert said. The officer arrested Wang and a criminal domestic-violence case was filed against him the following day.
His $50,000 bond was posted to get him out of jail, with her covering the cost, Medrano’s request for a temporary-restraining order says.
“I paid $500 down with a $200 recurring payment to be applied on the 29th monthly totaling $5,015.00 to secure the respondent’s release from jail,” she wrote. “He signed a notarized promissory note agreeing to pay me & not to come to my home or work. He has not paid me back, or (is) making monthly payments.”
On Sept. 16, Wang was served in court with a criminal protective order prohibiting him from being within 100 yards of Medrano, Haubert said. The order also prohibited Wang from owning, purchasing or possessing any firearm. And he had to stay away from her son and her brother.
In the request for the temporary-restraining order, Medrano wrote that Wang had a firearm at home that he used for his work as a security guard.
She had also sought protection for her relatives and her best friend, saying Wang would show up uninvited to the homes of her parents and the best friend in the early morning hours. The victim lived with her parents.
At times, he threatened to shatter the windows of her parents’ home, she said, and and at least once prompted her brother to call the police.
Medrano also said Wang threatened her son’s father during a custody exchange and followed them, causing her son emotional distress.
“This has created separation between my family and I, and I currently have nowhere to go,” she wrote.
Wang’s last court date was Oct. 7, and he was scheduled to appear again on Nov. 13, Haubert said.
Both Medrano and Wang died inside the restaurant. There were others inside as well, but no one else was injured.
