Three men wearing bandanas over their faces tied up a couple, assaulted them and stole about $4,700 in cash and jewelry during a home invasion robbery in Hacienda Heights on Sunday.

One of the robbers was armed with a knife, said Lt. Arthur Scott of the sheriff’s Industry Station. The woman suffered a small laceration to the lip but wasn’t taken to a hospital, he said. He described the two victims as being in their 60s.

The robbery in the 2000 block of Nadula Drive started at around 7 p.m. The resident arrived home and got accosted by three men in her garage.

Scott said the woman’s husband heard the garage door open, went to help his wife and encountered the suspects. He said the suspects forced the couple into the home then used garments and a belt to tie them up. The robbers put a pillow case over the man’s head, according to the lieutenant.

“(The husband) was sprayed with a window cleaner. He was also kicked and punched,” Scott said.

Scott said the woman sustained the cut to her lip when the suspects slammed her to the floor. After the robbers left, he said the woman wriggled free of her binds and called police.

Scott couldn’t verify media reports that the victims owned or worked in the jewelry business. The suspects were only described as three black men, 25 to 30 and 6 feet tall. They may have used an older model black BMW.

Investigators haven’t yet found a link to other home invasion robberies.

Homicide detectives are investigating the death of a man found fatally shot in a Hacienda Heights backyard Sunday afternoon.

Coroner’s officials didn’t release the man’s name on Monday because his next of kin hasn’t been notified.

A neighbor called deputies about 1:45 p.m. to report seeing someone lying in the large backyard of a home in the 14400 block of Clark Avenue, Sheriff’s Sgt. Rick Thurlo said.

Deputies and paramedics discovered the victim, a 34-year-old Latino, suffering from an apparent gunshot wound, according to department spokeswoman, Deputy Crystal Hernandez.

Paramedics pronounced the man dead at the scene.

Hernandez said according to witnesses, a single gunshot was heard in the area but no suspects or vehicles were seen.

Anyone with information is asked to call the Sheriff’s Homicide Bureau at 323-890-5500. Tips may also be submitted anonymously to L.A. Regional Crime Stoppers at 800-222-8477.

For the second time in recent years, a Hacienda Heights family has been devastated by a fatal tragedy. And for the second time, the community is rallying around the family to offer compassion and support.

Bertha Rosales, 42, died in a car crash while driving two of her four sons home from school in their hometown of Hacienda Heights, according to California Highway Patrol officials and friends.

Her sons Isaac, 13, and Ramon Jr., 10, suffered serious injuries in the crash, officials said. Isaac remained unconscious at a hospital with severe head injuries Wednesday, family friend Ernie Maldonado said. Ramon Jr. was making good progress in his recovery after undergoing surgery for injuries to his shoulder and elbow.

“This past Sunday was actually Bertha’s birthday,” Maldonado said.

The same family was affected by another deadly tragedy in August of 2011, when Rosales’ sister, 49-year-old Virginia Gonzales, and Gonzales’ 3-year-old son, Johnny Crowger, died in a house fire at their home in the 1700 block of Piermont Drive in Hacienda Heights.

Gonzales died while trying to rescue her son from the burning home, officials said.

In last week’s car crash, Rosales was driving a BMW sedan north on Durazno Drive, heading from a stop sign at a T-intersection, about 2:35 p.m. when the BMW collided with a Chevrolet Camaro heading west on Halliburton Road, CHP Sgt. Charles Quijada said.
