Palo Alto, CA – Police arrested a wanted felon early Monday morning after he was spotted prowling on the rooftop of a residential garage.

On Monday, January 29, 2018 at about 5:28 a.m., officers responded to the 500 block of Oxford Avenue on a report of a prowler. A neighbor had called police after seeing a man walking on the roof of their neighbor’s garage.

Officers arrived in less than two minutes, and saw the suspect standing on the roof of a residential garage. As officers ordered the man to come down, the suspect instead fled in the opposite direction, jumping down from the rooftop on the opposite side of where the officers were, and then disappearing over a fence.

Officers, as well as deputies from the Stanford Department of Public Safety, flooded the area in an attempt to find the suspect. Just after 6:00 a.m., a police dog from the Mountain View Police Department located the suspect hiding in bushes in the 500 block of Oxford Avenue. Police arrested him without incident. There was no evidence that he had attempted to break into any homes or the garage on which he was found.

Police booked 50-year-old Los Gatos resident Mark John Harmon into the Santa Clara County Main Jail for prowling and resisting arrest (fleeing from officers), both misdemeanors. Harmon also had two outstanding felony warrants for his arrest out of San Jose (one for attempted burglary and one for auto theft) for which he was also booked. His booking photo is attached to this release.
