Surveillance video shows the suspect climbing the steps of a residence up to the 94-year-old, ultimately slapping him across the face. The victim’s glasses went flying into the street, and the suspect then stomped on them.

Police say the victim, identified as Francisco Marte, suffered a small laceration to his nose.

“He tried to defend himself as much as he could, but at 94, you can’t do much,” his son, Elvis, told CBS2’s Reena Roy.

The family said in the more than 50 years they’ve lived in the neighborhood, nothing like this has ever happened before.

“My father is a well-known person and very much liked by everyone,” his daughter, Maria, said. “To see that happen, there is no compassion, especially for an older person. It’s very sad and very frustrating.”

“His own house – so it’s like you’re not safe anywhere,” said his son.

The suspect took off. He’s described as in his 50s, about 5’10”, wearing black boots, dark jeans and a grey hooded sweatshirt.
