LEMON GROVE, Calif. – A memorial is growing outside a Lemon Grove home Thursday where twin teenage girls were shot to death by their mother’s ex-boyfriend during a domestic-violence rampage.

Dwayne Edward Groves Jr., 38, was arrested shortly after the shooting, which was reported just after noon Wednesday at a home in the 7400 block of Central Avenue, sheriff’s Lt. Thomas Seiver said.

Deputies arrived to find the two 15-year-old girls dead inside the home and a man wounded. Paramedics took the surviving victim to a hospital to treat his injuries, which were not believed to be life-threatening, Seiver said.

A woman who identified herself as the mother of the victims told OnScene TV that the wounded victim was her 23-year-old son and the suspect was her ex-boyfriend.

“It’s a strike to the heart when you see children being murdered,” said San Diego County District Attorney Summer Stephan. It’s something that keeps us up at night.”

Domestic violence is a topic of grave concern during the coronavirus pandemic. 

Stephan said law enforcement officers across the county have seen an uptick in the number of domestic disturbances since the stay-at-home order took effect in late March. 

“When you have people who are essentially at home and are staying at home, you have less people who can observe injuries and the pain,” Stephan explained. 

Women and families should not be afraid to reach out for help even during a world crisis.

 “Although we may be physically distancing we are still here,” said Stephan. 

Groves was booked into San Diego Central Jail on suspicion of two counts of murder, two counts of attempted murder and one count of assault with a deadly weapon, according to jail records.

Groves was being held without bail pending his arraignment, tentatively scheduled for May 1.
