San Mateo Police Make Arrest in Brutal Hate Crime Attack

San Mateo police have arrested a 36-year-old man in connection with a brutal hate crime attack on Saturday.

Officers found the 55-year-old victim suffering from serious injuries to his head and face in the early morning hours of July 20, San Mateo Police Sgt. Dave Norris said.

The victim had sustained the injuries while walking from the area of Third and El Dorado Street to the 700 block of Santa Inez Avenue, according to Norris.

He indicated that he may have been targeted due to his sexual orientation, Norris said. The victim was transported to the nearest trauma center, where he was treated for his extensive injuries and is expected to survive.

San Mateo detectives worked over the following days to reconstruct the events leading up to the attack, and identified 36-year-old San Mateo resident Santos Manuel Marquez as the alleged attacker.

At about 5 p.m. on Wednesday, SMPD detectives attempted to contact Marquez at a residence in the 300 block of North Humboldt Street.

Marquez tried to flee through a window, and after a short chase and search, he was located and arrested without further incident.

The weapon Marquez allegedly used to perpetrate the vicious attack, a large bicycle "U-Lock," was also recovered and seized.

Marquez was booked into San Mateo County Jail on suspicion of attempted murder, assault with a deadly weapon, aggravated mayhem, and perpetration of a hate crime.
