Two men were shot and wounded at a home in Signal Hill Wednesday, and one of them was hospitalized in critical condition, police said.

The shooting happened about 11:15 p.m. Wednesday at a residence in the 3200 block of East 19th Street, the Signal Hill Police Department reported.

One man was wounded in the upper body and hospitalized in critical condition, police said. The other was wounded in the right leg and treated at a hospital and released, police said.

CBS2 reported a family of five was inside the home when three masked men forced their way in. The family told CBS2 the suspects tried to tie them up with zip-ties before they shot the victims and fled.

Police were unsure of a motive for the crime, which has not been classified as a home invasion, a sergeant said.

No arrests were reported, and no description was released of a suspect or suspects.

Anyone with information on the case was urged to call 562-989-7214.
