Seth Grinspan, 46, a known transient, was allegedly stabbed and killed by Alfred Delagraza, 48, also a transient, in the 15300 block of Pacific Coast Highway at about 7 p.m. Saturday night. Police said that apparently an altercation took place between the two men and ended when Grinspan was stabbed, across the highway from the lifeguard headquarters, near the mouth of Potrero Canyon. According to firefighters from Station 69 in Pacific Palisades, who were first on the scene, a blood trail enabled them to pinpoint the exact location where Grinspan was knifed. He had moved about a hundred yards toward Temescal Canyon Road before collapsing. He was dead when the firemen arrived. The suspect ran across PCH to the lifeguard tower. When the female lifeguard saw he had a knife, she slammed the door shut and called police. According to Palisades Senior Lead Officer Michael Moore, firefighters held the suspect until the police arrived and took Delagraza into custody. Grinspan was well known to Moore. ‘He did cause problems,’ Moore said. ‘He had been accused of physically attacking a woman who lived in the Palisades.’ Grinspan also had a prior history of arrests. ‘We knew him to be a violent homeless person who had previous altercations with law enforcement personnel and with local residents,’ said Scott Wagenseller, owner of Palisades Patrol. Delagraza, who was not known by Moore or members of Palisades Patrol, will be charged with murder.
