They pulled up from a night at dinner. Deservedly so, after a day’s worth of moving into the Granite Mobile Home Park right outside Woodstock.

Cheryl Caine came up from Florida to help with the move. She was in the car when she saw dozens of police officers.

“This whole area here was filled with cops. All of this area of the road was filled with cops and the cops had rifles walking around and asking questions,” she said.

Investigators were asking about what happened to 28-year-old Amber Cox. Police found her shot dead inside a trailer on Davis Avenue.

Cheryl says she saw Amber and her husband, 35-year-old Harry Rey, Jr., going at it a few days before.

“I hear this couple that I only know their names because my friends know their names arguing just about all day long and arguing about who’s going to leave and who’s not,” she said.

Baltimore County Police got the alert on Wednesday when three children, ages 6 and 7, were left at a Red Lobster near the Arundel Mills mall.

Turns out Rey dropped them off, then drove several miles down the road and shot himself inside his car on Sandy Farm Road in Severn.

“We’re not sure children were home, but it’s possible they were in the house when it happened. But the man shot his wife, killed his wife inside their home there on Davis Avenue,” Cpl. Shawn Vinson said.

Anne Arundel County Police found Rey’s body.

Investigators are now looking into if there were any red flags leading up to what police are calling a murder-suicide.

It’s an end Cheryl says even she didn’t expect after overhearing all of those fights.

“Thought this was a nice, quiet trailer park. But I guess things just happen that you can’t foresee,” she said.

As for those three children, they’re safe with relatives.

Police are working on figuring out a motive as to why this happened.

The three kids, 7-year-old twins and a 6-year-old, were not injured and have been released to the custody of family members.
