A Venice transient has been charged with murder after another transient died days after an apparent assault, police said.

Los Angeles police said it initially appeared that a 52-year-old man suffered head injuries after falling down in the 600 block of Rose Avenue in Venice at about 8 p.m. July 7. The incident was treated as a medical emergency at the time, and the Los Angeles Police Department was not notified.

The next day, however, a caller claimed to have witnessed an assault on the victim, alleging that the man was punched by another man and severely injured when he fell to the ground and hit his head, an LAPD spokesperson said.

LAPD Pacific homicide detectives then initiated an investigation as the victim remained in serious condition and learned that he was a transient from the Venice area, police said.

The suspect in the apparent attack was later identified as 50-year-old Frank Smith, also a transient, police said.

After the victim succumbed to his injuries July 10, police arrested Smith and charged him with murder, the LAPD spokesperson said. The victim has not been identified pending notification of his family.

Police are encouraging anyone who may have witnessed the assault or has additional information regarding this case to contact LAPD Pacific homicide detectives at (310) 482-6372 or (310) 482-6373.
